Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by running the app and observing behavior. Use when asked to verify a PR, confirm a fix works, test a change manually, check that a feature works, or validate local changes before pushing.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the current diff and apply the fixes — equivalent to /code-review --fix.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).\nTRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.\nSKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a pull request\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":14,"isInitial":true,"names":["frontend-design:frontend-design","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"f4254c80-5919-48d5-a77f-8f22966e14be","timestamp":"2026-06-04T15:58:11.017Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"f4254c80-5919-48d5-a77f-8f22966e14be","isSidechain":false,"attachment":{"type":"plan_mode","reminderType":"full","isSubAgent":false,"planFilePath":"/Users/jan/.claude/plans/do-a-security-audit-gleaming-toucan.md","planExists":false},"type":"attachment","uuid":"48fa8c9b-1d48-4576-bd72-36dc412fd5d2","timestamp":"2026-06-04T15:58:11.017Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"type":"ai-title","aiTitle":"Security audit of authentication system","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4"} +{"parentUuid":"48fa8c9b-1d48-4576-bd72-36dc412fd5d2","isSidechain":false,"message":{"model":"claude-opus-4-7","id":"msg_01CWbCeKaZKnY67Qc62EQd8i","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"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"}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":6,"cache_creation_input_tokens":16157,"cache_read_input_tokens":16387,"output_tokens":2337,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":16157,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":6,"output_tokens":2337,"cache_read_input_tokens":16387,"cache_creation_input_tokens":16157,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":16157},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CbiVh9huFSw6E5pixKDLf","type":"assistant","uuid":"779d1037-2174-4e1f-8131-9be5ec3f1009","timestamp":"2026-06-04T15:58:14.985Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"779d1037-2174-4e1f-8131-9be5ec3f1009","isSidechain":false,"message":{"model":"claude-opus-4-7","id":"msg_01CWbCeKaZKnY67Qc62EQd8i","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_01Mq1tEzVbbwqWMQKWLoUG51","name":"Agent","input":{"description":"Explore auth architecture","prompt":"Explore the authentication architecture in this Go codebase at /Users/jan/prg/ClusterCockpit/cc-backend.

AUTH MIDDLEWARE\n\n**File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go` (lines 435-589)**\n\nThe system uses **five separate middleware chains**:\n\n- `AuthAPI()` (lines 435-476): JWT-only, requires `RoleAPI` OR (`RoleAdmin` + `RoleAPI`)\n- `AuthUserAPI()` (lines 478-512): JWT-only, requires `RoleAPI` + (RoleUser|Manager|Support|Admin)\n- `AuthMetricStoreAPI()` (lines 514-548): JWT-only, requires `RoleAPI` + (RoleUser|Manager|Admin)\n- `AuthConfigAPI()` (lines 550-569): **Session-only**, requires `RoleAdmin` only\n- `AuthFrontendAPI()` (lines 571-587): Session-only, any authenticated user\n\nCredential extraction:\n- **JWT**: Headers `X-Auth-Token` or `Authorization: Bearer ...` (line 75-78)\n- **Sessions**: Gorilla cookie-based with keys from `SESSION_KEY` env var (lines 188-201)\n\nRejection: HTTP 401 with JSON error response via `onFailureResponse()` (server.go:61-68)\n\n### 2. CSRF PROTECTION\n\n**Status: PARTIAL**\n\n- **SameSite=Lax** set on session cookies (auth.go:327, oidc.go)\n- **PKCE protection** on OIDC flow (oidc.go comment line 104)\n- **NO traditional CSRF token** found in codebase (grep yielded only SameSite mentions)\n\nRisk: OIDC OAuth callback handling exists but no visible double-submit CSRF tokens on state-changing POST endpoints.\n\n### 3. CORS CONFIGURATION\n\n**File: `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/server.go` (lines 131-136)**\n\n```go\ncors.Handler(cors.Options{\n AllowCredentials: true,\n AllowedOrigins: []string{\"*\"}, // CRITICAL\n AllowedMethods: []string{\"GET\", \"POST\", \"HEAD\", \"OPTIONS\"},\n})\n```\n\n**CRITICAL RISK**: `AllowedOrigins: []string{\"*\"}` + `AllowCredentials: true` = **permissive CORS**. Any origin can make credentialed requests.\n\n### 4. TLS/HTTPS\n\n**File: `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/server.go` (lines 376-394)**\n\n- TLS configured: loads certs from `https-cert-file` and `https-key-file` (lines 376-390)\n- Cipher suites hardened: `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256`, `TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256`\n- MinVersion: TLS 1.2 (line 388)\n\n**Missing: NO HSTS header** (Strict-Transport-Security not found anywhere)\n\n**Session Secure flag**: Conditional (auth.go:318-326) — only set if `r.TLS != nil` OR `X-Forwarded-Proto: https`, otherwise warns (logs: \"Session cookies will not have Secure flag set\").\n\n### 5. LOGOUT\n\n**File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go` (lines 592-610)**\n\nInvalidates sessions by setting `session.Options.MaxAge = -1` and saving the expired session. Correctly handled via gorilla/sessions.\n\n**No explicit token revocation for JWTs**—tokens remain valid until expiration (max-age from config).\n\n### 6. API KEY / TOKEN ENDPOINTS\n\n**Token generation** (`/api/config/jwt/` via `getJWT()`):\n- **File**: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/rest.go` (lines 315-351)\n- **Authorization**: Admins can sign for any user; regular users only for themselves (line 329)\n- **Returns**: Raw JWT string (line 284: `generateJWT`)\n- **Endpoint**: `/frontend/jwt/` (session-auth required) — restricted to authenticated users\n\n**CLI token generation** (`--gen-jwt` flag):\n- **File**: `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/main.go` (lines 268-286)\n- Requires user to have `RoleAPI` (warning at line 276)\n- Invoked offline via CLI\n\n### 7. AUTHORIZATION (ROLE CHECKS)\n\n**Critical Gaps Found:**\n\n1. **`startJob()` REST endpoint** (job.go:717-787): **NO role check**. Only JWT auth middleware validates RoleAPI, but endpoint itself has no access control. NATS handler `handleStartJob()` (nats.go:227-294) also has **zero authorization checks**.\n\n2. **`stopJob()` REST endpoint** (job.go:805+): **NO explicit role check** in endpoint.\n\n3. **GraphQL mutations** (graph/schema.resolvers.go):\n - Lines 143-146, 195-196, etc. show role checks for tags\n - Lines 825, 892, 955 restrict some queries to Admin/Support\n - **Inconsistent**: not all mutations check roles\n\n4. **Config API endpoints** (rest.go:232, 277, 289): Properly check `RoleAdmin` before allowing notice updates, tagger operations.\n\n### 8. NATS API AUTH\n\n**File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/nats.go` (lines 129-157)**\n\n**CRITICAL: ZERO authentication on NATS messages.**\n\n```go\nfunc (api *NatsAPI) StartSubscriptions() error {\n client.Subscribe(s.SubjectJobEvent, func(subject string, data []byte) {\n api.jobCh <- natsMessage{...}\n })\n}\n```\n\n- Subscribes to configurable NATS subjects (`APISubjects.SubjectJobEvent`, `SubjectNodeState`)\n- **No auth check** on message handlers\n- `handleStartJob()` and `handleStopJob()` (lines 227-350) process messages **without validating sender identity or roles**\n- **Risk**: Anyone with NATS broker access can start/stop jobs, update node state\n\n---\n\n### SUMMARY OF HIGH-RISK FINDINGS\n\n| Issue | Severity | Location |\n|-------|----------|----------|\n| CORS allows `*` with credentials | **CRITICAL** | server.go:135 |\n| NATS API has zero auth checks | **CRITICAL** | nats.go:142-151 |\n| startJob/stopJob have no role validation | **HIGH** | job.go:717, nats.go:227 |\n| No HSTS header | **MEDIUM** | missing entirely |\n| No JWT token revocation | **MEDIUM** | jwt.go (design) |\n| Session Secure flag conditional | **MEDIUM** | auth.go:318-326 |\n\n**Total lines audited**: ~600 across auth/, api/, and cmd/ packages."}]}]},"uuid":"34d51df1-824d-4b4a-bb94-921581dfcf3a","timestamp":"2026-06-04T15:59:44.504Z","toolUseResult":{"status":"completed","prompt":"Explore how authentication is wired into the HTTP/GraphQL/REST request paths in this Go codebase at /Users/jan/prg/ClusterCockpit/cc-backend.

This is a classic open redirect enabling phishing attacks. The redirect should be validated to ensure it's relative or to a whitelisted domain.\n\n---\n\n### 2. **Secret Loading Issues**\n\n**JWT Keys:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/jwt.go` (lines 50-66): Keys loaded from `JWT_PUBLIC_KEY` and `JWT_PRIVATE_KEY` env vars. No hardcoded defaults.\n- `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/init.go` (lines 24-25): Default keys provided in sample `.env` file with clear warnings (\"DO NOT USE THESE TWO IN PRODUCTION!\").\n\n**Session Secret:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go` (lines 188-202): `SESSION_KEY` env var, or random bytes generated on startup if missing. The generated random key is non-persistent (session won't survive restarts).\n- Init file shows hardcoded sample: `SESSION_KEY=\"REDACTED\"` — documented as test-only.\n\n**LDAP Bind Password:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/ldap.go` (line 47): Loaded from `LDAP_ADMIN_PASSWORD`. Warning issued if unset, no hardcoded default.\n\n**OIDC Client Secret:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/oidc.go` (lines 73-76): Loaded from `OID_CLIENT_SECRET`. Warning issued if unset, no hardcoded default.\n\n**Finding:** Secrets are not logged anywhere in auth code. No information leakage detected in that respect.\n\n---\n\n### 3. **SQL Injection: User Repository**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go`\n\nSQL queries are properly parameterized:\n- Line 78-79: Uses `sq.Select().Where(..., username)` with parameterized query builder\n- Line 163: `sq.Insert(\"hpc_user\").Columns(cols...).Values(vals...)` — safe builder pattern\n- Line 224, 234, 241, 247: All `sq.Update()` calls use parameterized `Where()` clauses\n- Line 302: `DELETE` uses parameterized `WHERE ... = ?`\n\n**No SQL injection found.** The codebase uses Masterminds/squirrel query builder consistently.\n\n---\n\n### 4. **LDAP Injection Protection**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/ldap.go`\n\n- Line 91: `ldap.EscapeFilter(username)` — properly escapes LDAP filter metacharacters\n- Line 134: `ldap.EscapeDN(user.Username)` — properly escapes DN metacharacters\n\n**No LDAP injection vulnerability found.**\n\n---\n\n### 5. **OIDC: State/Nonce Validation**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/oidc.go`\n\n- Lines 96-114: State validation via cookie comparison (CSRF protection)\n- Lines 147-163: Nonce validation (replay attack protection) and ID token verification\n- Lines 289-299: State and nonce properly generated with random values\n\n**Replay protection is implemented correctly.**\n\n---\n\n### 6. **Error Messages: Information Disclosure**\n\n**Files:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/local.go` (line 44), `ldap.go` (line 138)\n\nBoth local and LDAP authenticators return generic error: `fmt.Errorf(\"Authentication failed\")`\n\n**Good:** No user enumeration via \"user not found\" vs \"bad password\" differences. All failures return the same generic message.\n\n---\n\n### 7. **Session Cookie Security**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go` (lines 315-327)\n\n- `SameSite=Lax` set (line 327) — good CSRF protection\n- **Warning issued** if not HTTPS (line 320)\n- `Secure` flag correctly set to `false` only for non-TLS, with explicit warning\n- `HttpOnly` NOT explicitly set in code! This is a potential XSS exposure risk if session is stored in cookies.\n\n**Issue:** No explicit `HttpOnly: true` found in `session.Options`. Gorilla sessions may default to HttpOnly=true, but this should be explicitly set.\n\n---\n\n### 8. **Frontend Token Storage**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/web/frontend/src/generic/utils.js` (line 31)\n\nJWT is passed via `Authorization: Bearer` header (not localStorage). Good.\n\n**localStorage usage** found in `/Users/jan/prg/ClusterCockpit/cc-backend/web/frontend/src/config/admin/Options.svelte` (lines 25-31) but only for non-sensitive UI state (`cc-scramble-names` flag), not for tokens.\n\n**No XSS-exposed JWT storage found.**\n\n---\n\n### 9. **Default Credentials**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/README.md`\n\nThe README example shows: `./cc-backend -init-db -add-user demo:admin:demo`\n\n**Documentation clearly states:** \"Please do not use it for production!\" before showing the demo command.

Let me write my report:\n\n## Security Audit Report: Auth-Adjacent Attack Surfaces\n\n### 1. **CRITICAL: Open Redirect Vulnerability**\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go` (lines 391-394)\n\nThe login handler directly uses user-supplied `redirect` form parameter without validation:\n```go\nif r.FormValue(\"redirect\") != \"\" {\n http.RedirectHandler(r.FormValue(\"redirect\"), http.StatusFound).ServeHTTP(rw, r.WithContext(ctx))\n```\nAn attacker can craft URLs like `login?redirect=https://evil.com` to redirect authenticated users post-login. This is a classic open redirect enabling phishing attacks. The redirect should be validated to ensure it's relative or to a whitelisted domain.\n\n---\n\n### 2. **Secret Loading Issues**\n\n**JWT Keys:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/jwt.go` (lines 50-66): Keys loaded from `JWT_PUBLIC_KEY` and `JWT_PRIVATE_KEY` env vars. No hardcoded defaults.\n- `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/init.go` (lines 24-25): Default keys provided in sample `.env` file with clear warnings (\"DO NOT USE THESE TWO IN PRODUCTION!\").\n\n**Session Secret:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go` (lines 188-202): `SESSION_KEY` env var, or random bytes generated on startup if missing. The generated random key is non-persistent (session won't survive restarts).\n- Init file shows hardcoded sample: `SESSION_KEY=\"REDACTED\"` — documented as test-only.\n\n**LDAP Bind Password:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/ldap.go` (line 47): Loaded from `LDAP_ADMIN_PASSWORD`. Warning issued if unset, no hardcoded default.\n\n**OIDC Client Secret:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/oidc.go` (lines 73-76): Loaded from `OID_CLIENT_SECRET`. Warning issued if unset, no hardcoded default.\n\n**Finding:** Secrets are not logged anywhere in auth code. No information leakage detected in that respect.\n\n---\n\n### 3. **SQL Injection: User Repository**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go`\n\nSQL queries are properly parameterized:\n- Line 78-79: Uses `sq.Select().Where(..., username)` with parameterized query builder\n- Line 163: `sq.Insert(\"hpc_user\").Columns(cols...).Values(vals...)` — safe builder pattern\n- Line 224, 234, 241, 247: All `sq.Update()` calls use parameterized `Where()` clauses\n- Line 302: `DELETE` uses parameterized `WHERE ... = ?`\n\n**No SQL injection found.** The codebase uses Masterminds/squirrel query builder consistently.\n\n---\n\n### 4. **LDAP Injection Protection**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/ldap.go`\n\n- Line 91: `ldap.EscapeFilter(username)` — properly escapes LDAP filter metacharacters\n- Line 134: `ldap.EscapeDN(user.Username)` — properly escapes DN metacharacters\n\n**No LDAP injection vulnerability found.**\n\n---\n\n### 5. **OIDC: State/Nonce Validation**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/oidc.go`\n\n- Lines 96-114: State validation via cookie comparison (CSRF protection)\n- Lines 147-163: Nonce validation (replay attack protection) and ID token verification\n- Lines 289-299: State and nonce properly generated with random values\n\n**Replay protection is implemented correctly.**\n\n---\n\n### 6. **Error Messages: Information Disclosure**\n\n**Files:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/local.go` (line 44), `ldap.go` (line 138)\n\nBoth local and LDAP authenticators return generic error: `fmt.Errorf(\"Authentication failed\")`\n\n**Good:** No user enumeration via \"user not found\" vs \"bad password\" differences. All failures return the same generic message.\n\n---\n\n### 7. **Session Cookie Security**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go` (lines 315-327)\n\n- `SameSite=Lax` set (line 327) — good CSRF protection\n- **Warning issued** if not HTTPS (line 320)\n- `Secure` flag correctly set to `false` only for non-TLS, with explicit warning\n- `HttpOnly` NOT explicitly set in code! This is a potential XSS exposure risk if session is stored in cookies.\n\n**Issue:** No explicit `HttpOnly: true` found in `session.Options`. Gorilla sessions may default to HttpOnly=true, but this should be explicitly set.\n\n---\n\n### 8. **Frontend Token Storage**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/web/frontend/src/generic/utils.js` (line 31)\n\nJWT is passed via `Authorization: Bearer` header (not localStorage). Good.\n\n**localStorage usage** found in `/Users/jan/prg/ClusterCockpit/cc-backend/web/frontend/src/config/admin/Options.svelte` (lines 25-31) but only for non-sensitive UI state (`cc-scramble-names` flag), not for tokens.\n\n**No XSS-exposed JWT storage found.**\n\n---\n\n### 9. **Default Credentials**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/README.md`\n\nThe README example shows: `./cc-backend -init-db -add-user demo:admin:demo`\n\n**Documentation clearly states:** \"Please do not use it for production!\" before showing the demo command. Users must explicitly use `-add-user` flag; no auto-seeded admin accounts.\n\n---\n\n### 10. **Dependencies**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/go.mod` (line 25)\n\n- `github.com/golang-jwt/jwt/v5` v5.3.1 — current version, Ed25519 support, no stale v3 usage\n- `golang.org/x/crypto` v0.52.0 — current, non-deprecated\n\n**No stale crypto libraries found.**\n\n---\n\n## Summary\n\n**Critical Issue:** Open redirect in login handler (lines 391-394 of auth.go) — user-supplied redirect parameter not validated.\n\n**Minor Issues:** \n- Session `HttpOnly` flag should be explicitly confirmed in cookie options\n- Session key is randomly regenerated on restart (non-persistent) — document this or use persistent default if needed\n\n**Strengths:** Proper parameterized SQL, LDAP/OIDC escaping, nonce/state validation, generic error messages, current dependencies, frontend JWT not in localStorage."}],"totalDurationMs":80092,"totalTokens":54933,"totalToolUseCount":48,"usage":{"input_tokens":3,"cache_creation_input_tokens":368,"cache_read_input_tokens":52733,"output_tokens":1829,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":368},"inference_geo":"not_available","iterations":[{"input_tokens":3,"output_tokens":1829,"cache_read_input_tokens":52733,"cache_creation_input_tokens":368,"cache_creation":{"ephemeral_5m_input_tokens":368,"ephemeral_1h_input_tokens":0},"type":"message"}],"speed":"standard"},"toolStats":{"readCount":14,"searchCount":0,"bashCount":34,"editFileCount":0,"linesAdded":0,"linesRemoved":0,"otherToolCount":0}},"sourceToolAssistantUUID":"2405a25f-d8f2-4036-b2a4-7eb1518e84c3","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"14e1e30d-80f0-4a1b-a000-c4d74ae150fb","isSidechain":false,"message":{"model":"claude-opus-4-7","id":"msg_012VcZweyF4Xk41g7dkmnSti","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"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"}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":10406,"cache_read_input_tokens":32544,"output_tokens":560,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":10406,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":1,"output_tokens":560,"cache_read_input_tokens":32544,"cache_creation_input_tokens":10406,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":10406},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CbiVqbuTjXkp6MSAr3hA7","type":"assistant","uuid":"a4a857f4-1db6-4d68-bd55-6e2c74fab3f0","timestamp":"2026-06-04T16:00:11.860Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"a4a857f4-1db6-4d68-bd55-6e2c74fab3f0","isSidechain":false,"message":{"model":"claude-opus-4-7","id":"msg_012VcZweyF4Xk41g7dkmnSti","type":"message","role":"assistant","content":[{"type":"text","text":"I have a comprehensive picture from the agents.

This document is the audit report: findings, severity, exact code locations, and concrete remediation. It is not a change plan — no code modifications are proposed here. After review, the user can ask for fixes to specific findings.\n\nScope audited:\n- `internal/auth/` — all authenticators, session handling, JWT, rate limiting\n- `cmd/cc-backend/server.go` — HTTP server setup, middleware wiring, CORS, TLS\n- `internal/api/nats.go` — NATS-based API auth posture\n- `internal/api/rest.go` — JWT issuance endpoint, role enforcement\n- Frontend token handling (`web/frontend/src/`) and dependency hygiene\n\n---\n\n## Findings by Severity\n\n### CRITICAL\n\n#### C1. Open redirect in login handler\n**Location:** `internal/auth/auth.go:391-394`\n```go\nif r.FormValue(\"redirect\") != \"\" {\n http.RedirectHandler(r.FormValue(\"redirect\"), http.StatusFound).ServeHTTP(rw, r.WithContext(ctx))\n return\n}\n```\nThe `redirect` form parameter is passed directly to `http.RedirectHandler` with no validation. After a successful login the server will 302-redirect to **any** URL the attacker controls (e.g. `https://evil.example.com`). Classic phishing primitive — the attacker lures a user to `/login?redirect=https://evil...`, the user enters real credentials, the URL bar briefly shows the legitimate domain, then drops to the attacker's site that imitates the dashboard.\n\n**Remediation:** Validate that `redirect` is a relative path (parse with `url.Parse`, reject if `u.Scheme != \"\" || u.Host != \"\"`) or strictly an allow-listed absolute URL. The redirect parameter is set by the auth-failure template at `server.go:214` (`Redirect: r.RequestURI`), which is always a path — so restricting to relative paths is compatible with the existing flow.\n\n#### C2. NATS API has zero authentication or authorization\n**Location:** `internal/api/nats.go:132-157`, handlers at lines 227-294 (`handleStartJob`), 299-382 (`handleStopJob`), 386-482 (`processNodestateEvent`).\n\nThe NATS subscribers process *any* message published to the configured subjects. There is no signing, no sender identity check, no role check. Anyone with publish rights on the NATS broker can:\n- Insert arbitrary jobs (including jobs attributed to other users)\n- Mark running jobs as stopped, triggering archive/finalization\n- Overwrite node health state for every node in any cluster\n\nThe REST equivalents (`startJob`, `stopJob`, node-state update) sit behind `AuthAPI` which requires `RoleAPI`. The NATS path bypasses that entirely.\n\n**Remediation options (pick one or layer):**\n1. Deployment-level: document that the NATS subjects MUST be ACL-restricted to trusted publishers (NATS account isolation, subject-level permissions). This needs to be in CLAUDE.md and the NATS setup docs explicitly, not just implied.\n2. Code-level: require a signed JWT field in the line-protocol payload (reuse `JWTAuthenticator` to verify it), reject messages without a valid token. This makes the NATS API safe even with a shared broker.\n\nAt minimum, today's CLAUDE.md mentions NATS auth in `config.json` (broker credentials) but does not call out the authorization gap. The audit recommends documenting **and** implementing token verification.\n\n---\n\n### HIGH\n\n#### H1. CORS allows any origin with credentials\n**Location:** `cmd/cc-backend/server.go:131-136`\n```go\ns.router.Use(cors.Handler(cors.Options{\n AllowCredentials: true,\n AllowedHeaders: []string{\"X-Requested-With\", \"Content-Type\", \"Authorization\", \"Origin\"},\n AllowedMethods: []string{\"GET\", \"POST\", \"HEAD\", \"OPTIONS\"},\n AllowedOrigins: []string{\"*\"},\n}))\n```\nBrowsers refuse to honor `Access-Control-Allow-Origin: *` together with `Access-Control-Allow-Credentials: true`, **but** the `go-chi/cors` package by default echoes back the request `Origin` when `AllowedOrigins: [\"*\"]` is set with credentials enabled. That makes credentialed cross-origin reads possible from any site — a malicious page can call `/frontend/*` or `/query` against the user's authenticated session and read the response. Combined with SameSite=Lax cookies (which permit top-level navigations), this is a real CSRF/data-exfiltration surface.\n\n**Remediation:** Replace `AllowedOrigins: [\"*\"]` with the actual allow-list of trusted origins, configured via `config.json`. If no cross-origin access is needed at all (default deployment is same-origin frontend), remove the CORS middleware or set `AllowCredentials: false`.\n\n#### H2. Session cookies are not explicitly HttpOnly\n**Location:** `internal/auth/auth.go:315-327` (`SaveSession`)\n\nThe `session.Options` block sets `MaxAge`, `Secure` (conditionally), and `SameSite` — but **does not set `HttpOnly`**. The `gorilla/sessions` `CookieStore` constructs `Options` with `HttpOnly: false` by default (only `Path` and `MaxAge` are pre-set). Result: the session cookie is readable by JavaScript via `document.cookie`. Any XSS in the frontend bundle escalates instantly to full session theft.\n\n**Remediation:** Add `session.Options.HttpOnly = true` in `SaveSession`. One-line fix.\n\n#### H3. SESSION_KEY fallback silently invalidates all sessions on restart\n**Location:** `internal/auth/auth.go:188-202`\n```go\nif sessKey == \"\" {\n cclog.Warn(...)\n bytes := make([]byte, 32)\n rand.Read(bytes)\n authInstance.sessionStore = sessions.NewCookieStore(bytes)\n}\n```\nIf the operator forgets `SESSION_KEY`, every restart generates a new random key. The warning is logged once at startup, easy to miss. Existing sessions become decryption failures on the next request — gorilla/sessions returns an error and the user is forced to re-authenticate. Worse, in a multi-replica deployment each replica generates its own key, so sessions don't validate across replicas.\n\nThis is reliability-critical rather than confidentiality-critical, but it's a foot-gun that should fail loudly.\n\n**Remediation:** Treat missing `SESSION_KEY` as a fatal error in production mode (the `-dev` flag could keep the random-fallback behavior). At minimum, log at `Error` level (not `Warn`) and include a sentence about persistence.\n\n---\n\n### MEDIUM\n\n#### M1. No HSTS header on HTTPS responses\n**Location:** `cmd/cc-backend/server.go:376-390` (TLS setup); no `Strict-Transport-Security` header is set anywhere.\n\nWhen TLS is enabled, the server should send HSTS to instruct browsers to refuse plaintext downgrades. Without it, an active network attacker on the first connection can intercept and strip TLS.\n\n**Remediation:** Add an HSTS middleware when `HTTPSCertFile` is configured: `Strict-Transport-Security: max-age=31536000; includeSubDomains`. The optional HTTP→HTTPS redirect already exists at server.go:370-374, so users opting in to TLS clearly intend HTTPS-only.\n\n#### M2. JWT issuer is read from unvalidated claims before signature verification\n**Location:** `internal/auth/jwtCookieSession.go:122-137`\n```go\ntoken, err := jwt.Parse(rawtoken, func(t *jwt.Token) (any, error) {\n if t.Method != jwt.SigningMethodEdDSA { ... }\n unvalidatedIssuer, success := t.Claims.(jwt.MapClaims)[\"iss\"].(string)\n if success && unvalidatedIssuer == jc.TrustedIssuer {\n return ja.publicKeyCrossLogin, nil\n }\n return ja.publicKey, nil\n})\n```\nThe key-selection callback reads `iss` from the **unverified** token to pick which public key to validate against. This is not directly exploitable — the signature still has to verify against whichever key is chosen, and the attacker doesn't have either private key — but it is the standard antipattern that `golang-jwt`'s docs warn about. It also means an attacker who compromises *either* the cross-login key or the local key can forge tokens claiming the other issuer, since the verifier silently falls back to the other key.\n\n**Remediation:** Validate `iss` after signature verification, and use `jwt.WithValidMethods([]string{\"EdDSA\"})` plus `jwt.WithIssuer(jc.TrustedIssuer)` parse options. Choose the key by the JWT `kid` header (key ID) if you need multiple keys.\n\n#### M3. No JWT revocation / blacklist\n**Location:** `internal/auth/jwt.go` — token claims include only `sub`, `roles`, `iat`, `exp`. Tokens are valid until `exp`. The `MaxAge` config controls lifetime.\n\nCompromised JWTs cannot be revoked before expiry — a leaked admin token (e.g. in CI logs) remains usable. CLI-generated tokens (`--gen-jwt`) typically have long lifetimes.\n\n**Remediation:** Either keep lifetimes short (e.g. 15 min, with re-issuance via session) or add a `jti` claim and a revocation list in the DB. The latter is overkill for most deployments — documenting \"if a token leaks, rotate the JWT_PRIVATE_KEY to invalidate all outstanding tokens\" is a reasonable alternative if it's actually documented.\n\n#### M4. No CSRF tokens on state-changing endpoints\n**Location:** No `gorilla/csrf` or custom CSRF tokens found anywhere.\n\nThe only CSRF mitigation is `SameSite=Lax` on the session cookie (auth.go:327). Lax permits top-level GET navigations but blocks cross-site POSTs, so it covers most attacks — but a same-site XSS on any path can still issue authenticated POSTs. There is no defense-in-depth.\n\nFor the `AuthConfigAPI` admin endpoints (notice updates, tagger ops, JWT minting), losing CSRF protection would mean total compromise. Today's posture relies entirely on browser SameSite enforcement.\n\n**Remediation:** Add CSRF tokens (`gorilla/csrf`) for the session-authenticated routes (`/frontend/*`, `/config/*`, `/logout`). JWT-authenticated `/api/*` routes don't need CSRF tokens since the Authorization header isn't auto-sent by browsers.\n\n---\n\n### LOW / INFORMATIONAL\n\n- **L1. No audience (`aud`) claim validation** — `internal/auth/jwt.go:128-138`. Tokens are not tied to this service. Low risk while `JWT_PRIVATE_KEY` is unique per deployment.\n- **L2. `securedCheck` IP allow-list trusts arbitrary headers** — `internal/auth/auth.go:619-625` reads `X-Real-Ip` and `X-Forwarded-For` unconditionally. If the server is not behind a trusted reverse proxy, a client can spoof its source IP. Document the reverse-proxy assumption in CLAUDE.md.\n- **L3. `Secure` cookie flag conditional on TLS detection** — `internal/auth/auth.go:318-326`. If the operator deploys behind a TLS-terminating proxy that doesn't set `X-Forwarded-Proto: https`, cookies go out without `Secure`. The code logs a warning but proceeds.\n- **L4. Login error messages are generic** ✅ — `local.go:44` and LDAP both return `\"Authentication failed\"`. No user-enumeration vector. Good.\n- **L5. LDAP injection** ✅ — `ldap.EscapeFilter` and `ldap.EscapeDN` are used. Good.\n- **L6. SQL injection** ✅ — `internal/repository/user.go` uses `Masterminds/squirrel` parameterized queries throughout. Good.\n- **L7. Password hashing** ✅ — bcrypt with `DefaultCost` (10). Acceptable. Could be raised to 12 for new hashes given modern hardware.\n- **L8. Frontend JWT storage** ✅ — `web/frontend/src/generic/utils.js:31` sends `Authorization: Bearer`; no localStorage token cache found.\n- **L9. Rate limiting** ✅ — 5 attempts per IP:username per 15 min (`auth.go:76`). Reasonable.\n- **L10. Dependency hygiene** ✅ — `github.com/golang-jwt/jwt/v5 v5.3.1`, `golang.org/x/crypto v0.52.0`. Current.\n- **L11. OIDC state and nonce validation** ✅ — `internal/auth/oidc.go` validates both. Good.\n\n---\n\n## Recommended remediation priority\n\n1. **C1 + C2** — open redirect and NATS authz. Both are exploitable in realistic deployments. C1 is a one-line fix; C2 requires either docs + ACL guidance, or a token requirement in messages.\n2. **H1 + H2** — CORS and HttpOnly. Both are small code changes with significant defense-in-depth impact.\n3. **H3, M1, M2** — fail loud on missing SESSION_KEY, add HSTS, fix issuer check order.\n4. **M3, M4** — JWT lifetime/revocation policy and CSRF tokens. Larger design changes; defer unless threat model demands them.\n\n## Verification\n\nThis audit reads code only; nothing was executed. To validate findings after fixes:\n- C1: `curl -i -d 'username=...&password=...&redirect=https://evil.example.com/' http://localhost:8080/login` should not return a `Location: https://evil.example.com/` header.\n- H1: `curl -i -H 'Origin: https://evil.example.com' http://localhost:8080/frontend/...` — the response should not echo `Access-Control-Allow-Origin: https://evil.example.com` with credentials.\n- H2: `curl -i -d 'username=...&password=...' http://localhost:8080/login` — the `Set-Cookie: session=...` header should include `HttpOnly`.\n\n## Out of scope\n\n- Authorization correctness at the GraphQL resolver level (e.g. whether each mutation checks roles consistently). The audit noted inconsistencies in `internal/graph/schema.resolvers.go` but did not enumerate them. Worth a follow-up review.\n- Job-archive backend (S3 credentials, file permissions).\n- Metricstore client (`internal/metricstoreclient`) auth to upstream `cc-metric-store`.\n- Frontend XSS audit (Svelte template injection surfaces).\n"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":7567,"cache_read_input_tokens":69830,"output_tokens":7113,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":7567,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":1,"output_tokens":7113,"cache_read_input_tokens":69830,"cache_creation_input_tokens":7567,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":7567},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CbiVt8HNhRhDrirH2752m","type":"assistant","uuid":"0448f260-7846-4263-9b73-aa8d2e4923d8","timestamp":"2026-06-04T16:02:22.138Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"0448f260-7846-4263-9b73-aa8d2e4923d8","isSidechain":false,"promptId":"6e769002-ed9a-4e49-bd3e-f4c062c9f888","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_012ccp7qkr3APAKiXbqk49vo","type":"tool_result","content":"File created successfully at: /Users/jan/.claude/plans/do-a-security-audit-gleaming-toucan.md (file state is current in your context — no need to Read it back)"}]},"uuid":"338bf36f-906d-4e93-a325-4f4cec5afd9e","timestamp":"2026-06-04T16:02:22.172Z","toolUseResult":{"type":"create","filePath":"/Users/jan/.claude/plans/do-a-security-audit-gleaming-toucan.md","content":"# Security Audit — cc-backend Authentication\n\n## Context\n\nThe user requested a security audit of the authentication subsystem in cc-backend.

Current.\n- **L11. OIDC state and nonce validation** ✅ — `internal/auth/oidc.go` validates both. Good.\n\n---\n\n## Recommended remediation priority\n\n1. **C1 + C2** — open redirect and NATS authz. Both are exploitable in realistic deployments. C1 is a one-line fix; C2 requires either docs + ACL guidance, or a token requirement in messages.\n2. **H1 + H2** — CORS and HttpOnly. Both are small code changes with significant defense-in-depth impact.\n3. **H3, M1, M2** — fail loud on missing SESSION_KEY, add HSTS, fix issuer check order.\n4. **M3, M4** — JWT lifetime/revocation policy and CSRF tokens. Larger design changes; defer unless threat model demands them.\n\n## Verification\n\nThis audit reads code only; nothing was executed. To validate findings after fixes:\n- C1: `curl -i -d 'username=...&password=...&redirect=https://evil.example.com/' http://localhost:8080/login` should not return a `Location: https://evil.example.com/` header.\n- H1: `curl -i -H 'Origin: https://evil.example.com' http://localhost:8080/frontend/...` — the response should not echo `Access-Control-Allow-Origin: https://evil.example.com` with credentials.\n- H2: `curl -i -d 'username=...&password=...' http://localhost:8080/login` — the `Set-Cookie: session=...` header should include `HttpOnly`.\n\n## Out of scope\n\n- Authorization correctness at the GraphQL resolver level (e.g. whether each mutation checks roles consistently). The audit noted inconsistencies in `internal/graph/schema.resolvers.go` but did not enumerate them. Worth a follow-up review.\n- Job-archive backend (S3 credentials, file permissions).\n- Metricstore client (`internal/metricstoreclient`) auth to upstream `cc-metric-store`.\n- Frontend XSS audit (Svelte template injection surfaces).\n","structuredPatch":[],"originalFile":null,"userModified":false},"sourceToolAssistantUUID":"0448f260-7846-4263-9b73-aa8d2e4923d8","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"}

Security Audit — cc-backend Authentication\n\n## Context\n\nThe user requested a security audit of the authentication subsystem in cc-backend. This document is the audit report: findings, severity, exact code locations, and concrete remediation. It is not a change plan — no code modifications are proposed here. After review, the user can ask for fixes to specific findings.\n\nScope audited:\n- `internal/auth/` — all authenticators, session handling, JWT, rate limiting\n- `cmd/cc-backend/server.go` — HTTP server setup, middleware wiring, CORS, TLS\n- `internal/api/nats.go` — NATS-based API auth posture\n- `internal/api/rest.go` — JWT issuance endpoint, role enforcement\n- Frontend token handling (`web/frontend/src/`) and dependency hygiene\n\n---\n\n## Findings by Severity\n\n### CRITICAL\n\n#### C1. Open redirect in login handler\n**Location:** `internal/auth/auth.go:391-394`\n```go\nif r.FormValue(\"redirect\") != \"\" {\n http.RedirectHandler(r.FormValue(\"redirect\"), http.StatusFound).ServeHTTP(rw, r.WithContext(ctx))\n return\n}\n```\nThe `redirect` form parameter is passed directly to `http.RedirectHandler` with no validation. After a successful login the server will 302-redirect to **any** URL the attacker controls (e.g. `https://evil.example.com`). Classic phishing primitive — the attacker lures a user to `/login?redirect=https://evil...`, the user enters real credentials, the URL bar briefly shows the legitimate domain, then drops to the attacker's site that imitates the dashboard.\n\n**Remediation:** Validate that `redirect` is a relative path (parse with `url.Parse`, reject if `u.Scheme != \"\" || u.Host != \"\"`) or strictly an allow-listed absolute URL. The redirect parameter is set by the auth-failure template at `server.go:214` (`Redirect: r.RequestURI`), which is always a path — so restricting to relative paths is compatible with the existing flow.\n\n#### C2. NATS API has zero authentication or authorization\n**Location:** `internal/api/nats.go:132-157`, handlers at lines 227-294 (`handleStartJob`), 299-382 (`handleStopJob`), 386-482 (`processNodestateEvent`).\n\nThe NATS subscribers process *any* message published to the configured subjects. There is no signing, no sender identity check, no role check. Anyone with publish rights on the NATS broker can:\n- Insert arbitrary jobs (including jobs attributed to other users)\n- Mark running jobs as stopped, triggering archive/finalization\n- Overwrite node health state for every node in any cluster\n\nThe REST equivalents (`startJob`, `stopJob`, node-state update) sit behind `AuthAPI` which requires `RoleAPI`. The NATS path bypasses that entirely.\n\n**Remediation options (pick one or layer):**\n1. Deployment-level: document that the NATS subjects MUST be ACL-restricted to trusted publishers (NATS account isolation, subject-level permissions). This needs to be in CLAUDE.md and the NATS setup docs explicitly, not just implied.\n2. Code-level: require a signed JWT field in the line-protocol payload (reuse `JWTAuthenticator` to verify it), reject messages without a valid token. This makes the NATS API safe even with a shared broker.\n\nAt minimum, today's CLAUDE.md mentions NATS auth in `config.json` (broker credentials) but does not call out the authorization gap. The audit recommends documenting **and** implementing token verification.\n\n---\n\n### HIGH\n\n#### H1. CORS allows any origin with credentials\n**Location:** `cmd/cc-backend/server.go:131-136`\n```go\ns.router.Use(cors.Handler(cors.Options{\n AllowCredentials: true,\n AllowedHeaders: []string{\"X-Requested-With\", \"Content-Type\", \"Authorization\", \"Origin\"},\n AllowedMethods: []string{\"GET\", \"POST\", \"HEAD\", \"OPTIONS\"},\n AllowedOrigins: []string{\"*\"},\n}))\n```\nBrowsers refuse to honor `Access-Control-Allow-Origin: *` together with `Access-Control-Allow-Credentials: true`, **but** the `go-chi/cors` package by default echoes back the request `Origin` when `AllowedOrigins: [\"*\"]` is set with credentials enabled. That makes credentialed cross-origin reads possible from any site — a malicious page can call `/frontend/*` or `/query` against the user's authenticated session and read the response. Combined with SameSite=Lax cookies (which permit top-level navigations), this is a real CSRF/data-exfiltration surface.\n\n**Remediation:** Replace `AllowedOrigins: [\"*\"]` with the actual allow-list of trusted origins, configured via `config.json`. If no cross-origin access is needed at all (default deployment is same-origin frontend), remove the CORS middleware or set `AllowCredentials: false`.\n\n#### H2. Session cookies are not explicitly HttpOnly\n**Location:** `internal/auth/auth.go:315-327` (`SaveSession`)\n\nThe `session.Options` block sets `MaxAge`, `Secure` (conditionally), and `SameSite` — but **does not set `HttpOnly`**. The `gorilla/sessions` `CookieStore` constructs `Options` with `HttpOnly: false` by default (only `Path` and `MaxAge` are pre-set). Result: the session cookie is readable by JavaScript via `document.cookie`. Any XSS in the frontend bundle escalates instantly to full session theft.\n\n**Remediation:** Add `session.Options.HttpOnly = true` in `SaveSession`. One-line fix.\n\n#### H3. SESSION_KEY fallback silently invalidates all sessions on restart\n**Location:** `internal/auth/auth.go:188-202`\n```go\nif sessKey == \"\" {\n cclog.Warn(...)\n bytes := make([]byte, 32)\n rand.Read(bytes)\n authInstance.sessionStore = sessions.NewCookieStore(bytes)\n}\n```\nIf the operator forgets `SESSION_KEY`, every restart generates a new random key. The warning is logged once at startup, easy to miss. Existing sessions become decryption failures on the next request — gorilla/sessions returns an error and the user is forced to re-authenticate. Worse, in a multi-replica deployment each replica generates its own key, so sessions don't validate across replicas.\n\nThis is reliability-critical rather than confidentiality-critical, but it's a foot-gun that should fail loudly.\n\n**Remediation:** Treat missing `SESSION_KEY` as a fatal error in production mode (the `-dev` flag could keep the random-fallback behavior). At minimum, log at `Error` level (not `Warn`) and include a sentence about persistence.\n\n---\n\n### MEDIUM\n\n#### M1. No HSTS header on HTTPS responses\n**Location:** `cmd/cc-backend/server.go:376-390` (TLS setup); no `Strict-Transport-Security` header is set anywhere.\n\nWhen TLS is enabled, the server should send HSTS to instruct browsers to refuse plaintext downgrades. Without it, an active network attacker on the first connection can intercept and strip TLS.\n\n**Remediation:** Add an HSTS middleware when `HTTPSCertFile` is configured: `Strict-Transport-Security: max-age=31536000; includeSubDomains`. The optional HTTP→HTTPS redirect already exists at server.go:370-374, so users opting in to TLS clearly intend HTTPS-only.\n\n#### M2. JWT issuer is read from unvalidated claims before signature verification\n**Location:** `internal/auth/jwtCookieSession.go:122-137`\n```go\ntoken, err := jwt.Parse(rawtoken, func(t *jwt.Token) (any, error) {\n if t.Method != jwt.SigningMethodEdDSA { ... }\n unvalidatedIssuer, success := t.Claims.(jwt.MapClaims)[\"iss\"].(string)\n if success && unvalidatedIssuer == jc.TrustedIssuer {\n return ja.publicKeyCrossLogin, nil\n }\n return ja.publicKey, nil\n})\n```\nThe key-selection callback reads `iss` from the **unverified** token to pick which public key to validate against. This is not directly exploitable — the signature still has to verify against whichever key is chosen, and the attacker doesn't have either private key — but it is the standard antipattern that `golang-jwt`'s docs warn about. It also means an attacker who compromises *either* the cross-login key or the local key can forge tokens claiming the other issuer, since the verifier silently falls back to the other key.\n\n**Remediation:** Validate `iss` after signature verification, and use `jwt.WithValidMethods([]string{\"EdDSA\"})` plus `jwt.WithIssuer(jc.TrustedIssuer)` parse options. Choose the key by the JWT `kid` header (key ID) if you need multiple keys.\n\n#### M3. No JWT revocation / blacklist\n**Location:** `internal/auth/jwt.go` — token claims include only `sub`, `roles`, `iat`, `exp`. Tokens are valid until `exp`. The `MaxAge` config controls lifetime.\n\nCompromised JWTs cannot be revoked before expiry — a leaked admin token (e.g. in CI logs) remains usable. CLI-generated tokens (`--gen-jwt`) typically have long lifetimes.\n\n**Remediation:** Either keep lifetimes short (e.g. 15 min, with re-issuance via session) or add a `jti` claim and a revocation list in the DB. The latter is overkill for most deployments — documenting \"if a token leaks, rotate the JWT_PRIVATE_KEY to invalidate all outstanding tokens\" is a reasonable alternative if it's actually documented.\n\n#### M4. No CSRF tokens on state-changing endpoints\n**Location:** No `gorilla/csrf` or custom CSRF tokens found anywhere.\n\nThe only CSRF mitigation is `SameSite=Lax` on the session cookie (auth.go:327). Lax permits top-level GET navigations but blocks cross-site POSTs, so it covers most attacks — but a same-site XSS on any path can still issue authenticated POSTs. There is no defense-in-depth.\n\nFor the `AuthConfigAPI` admin endpoints (notice updates, tagger ops, JWT minting), losing CSRF protection would mean total compromise. Today's posture relies entirely on browser SameSite enforcement.\n\n**Remediation:** Add CSRF tokens (`gorilla/csrf`) for the session-authenticated routes (`/frontend/*`, `/config/*`, `/logout`). JWT-authenticated `/api/*` routes don't need CSRF tokens since the Authorization header isn't auto-sent by browsers.\n\n---\n\n### LOW / INFORMATIONAL\n\n- **L1. No audience (`aud`) claim validation** — `internal/auth/jwt.go:128-138`. Tokens are not tied to this service. Low risk while `JWT_PRIVATE_KEY` is unique per deployment.\n- **L2. `securedCheck` IP allow-list trusts arbitrary headers** — `internal/auth/auth.go:619-625` reads `X-Real-Ip` and `X-Forwarded-For` unconditionally. If the server is not behind a trusted reverse proxy, a client can spoof its source IP. Document the reverse-proxy assumption in CLAUDE.md.\n- **L3. `Secure` cookie flag conditional on TLS detection** — `internal/auth/auth.go:318-326`. If the operator deploys behind a TLS-terminating proxy that doesn't set `X-Forwarded-Proto: https`, cookies go out without `Secure`. The code logs a warning but proceeds.\n- **L4. Login error messages are generic** ✅ — `local.go:44` and LDAP both return `\"Authentication failed\"`. No user-enumeration vector. Good.\n- **L5. LDAP injection** ✅ — `ldap.EscapeFilter` and `ldap.EscapeDN` are used. Good.\n- **L6. SQL injection** ✅ — `internal/repository/user.go` uses `Masterminds/squirrel` parameterized queries throughout. Good.\n- **L7. Password hashing** ✅ — bcrypt with `DefaultCost` (10). Acceptable. Could be raised to 12 for new hashes given modern hardware.\n- **L8. Frontend JWT storage** ✅ — `web/frontend/src/generic/utils.js:31` sends `Authorization: Bearer`; no localStorage token cache found.\n- **L9. Rate limiting** ✅ — 5 attempts per IP:username per 15 min (`auth.go:76`). Reasonable.\n- **L10. Dependency hygiene** ✅ — `github.com/golang-jwt/jwt/v5 v5.3.1`, `golang.org/x/crypto v0.52.0`. Current.\n- **L11. OIDC state and nonce validation** ✅ — `internal/auth/oidc.go` validates both. Good.\n\n---\n\n## Recommended remediation priority\n\n1. **C1 + C2** — open redirect and NATS authz. Both are exploitable in realistic deployments. C1 is a one-line fix; C2 requires either docs + ACL guidance, or a token requirement in messages.\n2. **H1 + H2** — CORS and HttpOnly. Both are small code changes with significant defense-in-depth impact.\n3. **H3, M1, M2** — fail loud on missing SESSION_KEY, add HSTS, fix issuer check order.\n4. **M3, M4** — JWT lifetime/revocation policy and CSRF tokens. Larger design changes; defer unless threat model demands them.\n\n## Verification\n\nThis audit reads code only; nothing was executed.

This document is the audit report: findings, severity, exact code locations, and concrete remediation. It is not a change plan — no code modifications are proposed here. After review, the user can ask for fixes to specific findings.\n\nScope audited:\n- `internal/auth/` — all authenticators, session handling, JWT, rate limiting\n- `cmd/cc-backend/server.go` — HTTP server setup, middleware wiring, CORS, TLS\n- `internal/api/nats.go` — NATS-based API auth posture\n- `internal/api/rest.go` — JWT issuance endpoint, role enforcement\n- Frontend token handling (`web/frontend/src/`) and dependency hygiene\n\n---\n\n## Findings by Severity\n\n### CRITICAL\n\n#### C1. Open redirect in login handler\n**Location:** `internal/auth/auth.go:391-394`\n```go\nif r.FormValue(\"redirect\") != \"\" {\n http.RedirectHandler(r.FormValue(\"redirect\"), http.StatusFound).ServeHTTP(rw, r.WithContext(ctx))\n return\n}\n```\nThe `redirect` form parameter is passed directly to `http.RedirectHandler` with no validation. After a successful login the server will 302-redirect to **any** URL the attacker controls (e.g. `https://evil.example.com`). Classic phishing primitive — the attacker lures a user to `/login?redirect=https://evil...`, the user enters real credentials, the URL bar briefly shows the legitimate domain, then drops to the attacker's site that imitates the dashboard.\n\n**Remediation:** Validate that `redirect` is a relative path (parse with `url.Parse`, reject if `u.Scheme != \"\" || u.Host != \"\"`) or strictly an allow-listed absolute URL. The redirect parameter is set by the auth-failure template at `server.go:214` (`Redirect: r.RequestURI`), which is always a path — so restricting to relative paths is compatible with the existing flow.\n\n#### C2. NATS API has zero authentication or authorization\n**Location:** `internal/api/nats.go:132-157`, handlers at lines 227-294 (`handleStartJob`), 299-382 (`handleStopJob`), 386-482 (`processNodestateEvent`).\n\nThe NATS subscribers process *any* message published to the configured subjects. There is no signing, no sender identity check, no role check. Anyone with publish rights on the NATS broker can:\n- Insert arbitrary jobs (including jobs attributed to other users)\n- Mark running jobs as stopped, triggering archive/finalization\n- Overwrite node health state for every node in any cluster\n\nThe REST equivalents (`startJob`, `stopJob`, node-state update) sit behind `AuthAPI` which requires `RoleAPI`. The NATS path bypasses that entirely.\n\n**Remediation options (pick one or layer):**\n1. Deployment-level: document that the NATS subjects MUST be ACL-restricted to trusted publishers (NATS account isolation, subject-level permissions). This needs to be in CLAUDE.md and the NATS setup docs explicitly, not just implied.\n2. Code-level: require a signed JWT field in the line-protocol payload (reuse `JWTAuthenticator` to verify it), reject messages without a valid token. This makes the NATS API safe even with a shared broker.\n\nAt minimum, today's CLAUDE.md mentions NATS auth in `config.json` (broker credentials) but does not call out the authorization gap. The audit recommends documenting **and** implementing token verification.\n\n---\n\n### HIGH\n\n#### H1. CORS allows any origin with credentials\n**Location:** `cmd/cc-backend/server.go:131-136`\n```go\ns.router.Use(cors.Handler(cors.Options{\n AllowCredentials: true,\n AllowedHeaders: []string{\"X-Requested-With\", \"Content-Type\", \"Authorization\", \"Origin\"},\n AllowedMethods: []string{\"GET\", \"POST\", \"HEAD\", \"OPTIONS\"},\n AllowedOrigins: []string{\"*\"},\n}))\n```\nBrowsers refuse to honor `Access-Control-Allow-Origin: *` together with `Access-Control-Allow-Credentials: true`, **but** the `go-chi/cors` package by default echoes back the request `Origin` when `AllowedOrigins: [\"*\"]` is set with credentials enabled. That makes credentialed cross-origin reads possible from any site — a malicious page can call `/frontend/*` or `/query` against the user's authenticated session and read the response. Combined with SameSite=Lax cookies (which permit top-level navigations), this is a real CSRF/data-exfiltration surface.\n\n**Remediation:** Replace `AllowedOrigins: [\"*\"]` with the actual allow-list of trusted origins, configured via `config.json`. If no cross-origin access is needed at all (default deployment is same-origin frontend), remove the CORS middleware or set `AllowCredentials: false`.\n\n#### H2. Session cookies are not explicitly HttpOnly\n**Location:** `internal/auth/auth.go:315-327` (`SaveSession`)\n\nThe `session.Options` block sets `MaxAge`, `Secure` (conditionally), and `SameSite` — but **does not set `HttpOnly`**. The `gorilla/sessions` `CookieStore` constructs `Options` with `HttpOnly: false` by default (only `Path` and `MaxAge` are pre-set). Result: the session cookie is readable by JavaScript via `document.cookie`. Any XSS in the frontend bundle escalates instantly to full session theft.\n\n**Remediation:** Add `session.Options.HttpOnly = true` in `SaveSession`. One-line fix.\n\n#### H3. SESSION_KEY fallback silently invalidates all sessions on restart\n**Location:** `internal/auth/auth.go:188-202`\n```go\nif sessKey == \"\" {\n cclog.Warn(...)\n bytes := make([]byte, 32)\n rand.Read(bytes)\n authInstance.sessionStore = sessions.NewCookieStore(bytes)\n}\n```\nIf the operator forgets `SESSION_KEY`, every restart generates a new random key. The warning is logged once at startup, easy to miss. Existing sessions become decryption failures on the next request — gorilla/sessions returns an error and the user is forced to re-authenticate. Worse, in a multi-replica deployment each replica generates its own key, so sessions don't validate across replicas.\n\nThis is reliability-critical rather than confidentiality-critical, but it's a foot-gun that should fail loudly.\n\n**Remediation:** Treat missing `SESSION_KEY` as a fatal error in production mode (the `-dev` flag could keep the random-fallback behavior). At minimum, log at `Error` level (not `Warn`) and include a sentence about persistence.\n\n---\n\n### MEDIUM\n\n#### M1. No HSTS header on HTTPS responses\n**Location:** `cmd/cc-backend/server.go:376-390` (TLS setup); no `Strict-Transport-Security` header is set anywhere.\n\nWhen TLS is enabled, the server should send HSTS to instruct browsers to refuse plaintext downgrades. Without it, an active network attacker on the first connection can intercept and strip TLS.\n\n**Remediation:** Add an HSTS middleware when `HTTPSCertFile` is configured: `Strict-Transport-Security: max-age=31536000; includeSubDomains`. The optional HTTP→HTTPS redirect already exists at server.go:370-374, so users opting in to TLS clearly intend HTTPS-only.\n\n#### M2. JWT issuer is read from unvalidated claims before signature verification\n**Location:** `internal/auth/jwtCookieSession.go:122-137`\n```go\ntoken, err := jwt.Parse(rawtoken, func(t *jwt.Token) (any, error) {\n if t.Method != jwt.SigningMethodEdDSA { ... }\n unvalidatedIssuer, success := t.Claims.(jwt.MapClaims)[\"iss\"].(string)\n if success && unvalidatedIssuer == jc.TrustedIssuer {\n return ja.publicKeyCrossLogin, nil\n }\n return ja.publicKey, nil\n})\n```\nThe key-selection callback reads `iss` from the **unverified** token to pick which public key to validate against. This is not directly exploitable — the signature still has to verify against whichever key is chosen, and the attacker doesn't have either private key — but it is the standard antipattern that `golang-jwt`'s docs warn about. It also means an attacker who compromises *either* the cross-login key or the local key can forge tokens claiming the other issuer, since the verifier silently falls back to the other key.\n\n**Remediation:** Validate `iss` after signature verification, and use `jwt.WithValidMethods([]string{\"EdDSA\"})` plus `jwt.WithIssuer(jc.TrustedIssuer)` parse options. Choose the key by the JWT `kid` header (key ID) if you need multiple keys.\n\n#### M3. No JWT revocation / blacklist\n**Location:** `internal/auth/jwt.go` — token claims include only `sub`, `roles`, `iat`, `exp`. Tokens are valid until `exp`. The `MaxAge` config controls lifetime.\n\nCompromised JWTs cannot be revoked before expiry — a leaked admin token (e.g. in CI logs) remains usable. CLI-generated tokens (`--gen-jwt`) typically have long lifetimes.\n\n**Remediation:** Either keep lifetimes short (e.g. 15 min, with re-issuance via session) or add a `jti` claim and a revocation list in the DB. The latter is overkill for most deployments — documenting \"if a token leaks, rotate the JWT_PRIVATE_KEY to invalidate all outstanding tokens\" is a reasonable alternative if it's actually documented.\n\n#### M4. No CSRF tokens on state-changing endpoints\n**Location:** No `gorilla/csrf` or custom CSRF tokens found anywhere.\n\nThe only CSRF mitigation is `SameSite=Lax` on the session cookie (auth.go:327). Lax permits top-level GET navigations but blocks cross-site POSTs, so it covers most attacks — but a same-site XSS on any path can still issue authenticated POSTs. There is no defense-in-depth.\n\nFor the `AuthConfigAPI` admin endpoints (notice updates, tagger ops, JWT minting), losing CSRF protection would mean total compromise. Today's posture relies entirely on browser SameSite enforcement.\n\n**Remediation:** Add CSRF tokens (`gorilla/csrf`) for the session-authenticated routes (`/frontend/*`, `/config/*`, `/logout`). JWT-authenticated `/api/*` routes don't need CSRF tokens since the Authorization header isn't auto-sent by browsers.\n\n---\n\n### LOW / INFORMATIONAL\n\n- **L1. No audience (`aud`) claim validation** — `internal/auth/jwt.go:128-138`. Tokens are not tied to this service. Low risk while `JWT_PRIVATE_KEY` is unique per deployment.\n- **L2. `securedCheck` IP allow-list trusts arbitrary headers** — `internal/auth/auth.go:619-625` reads `X-Real-Ip` and `X-Forwarded-For` unconditionally. If the server is not behind a trusted reverse proxy, a client can spoof its source IP. Document the reverse-proxy assumption in CLAUDE.md.\n- **L3. `Secure` cookie flag conditional on TLS detection** — `internal/auth/auth.go:318-326`. If the operator deploys behind a TLS-terminating proxy that doesn't set `X-Forwarded-Proto: https`, cookies go out without `Secure`. The code logs a warning but proceeds.\n- **L4. Login error messages are generic** ✅ — `local.go:44` and LDAP both return `\"Authentication failed\"`. No user-enumeration vector. Good.\n- **L5. LDAP injection** ✅ — `ldap.EscapeFilter` and `ldap.EscapeDN` are used. Good.\n- **L6. SQL injection** ✅ — `internal/repository/user.go` uses `Masterminds/squirrel` parameterized queries throughout. Good.\n- **L7. Password hashing** ✅ — bcrypt with `DefaultCost` (10). Acceptable. Could be raised to 12 for new hashes given modern hardware.\n- **L8. Frontend JWT storage** ✅ — `web/frontend/src/generic/utils.js:31` sends `Authorization: Bearer`; no localStorage token cache found.\n- **L9. Rate limiting** ✅ — 5 attempts per IP:username per 15 min (`auth.go:76`). Reasonable.\n- **L10. Dependency hygiene** ✅ — `github.com/golang-jwt/jwt/v5 v5.3.1`, `golang.org/x/crypto v0.52.0`. Current.\n- **L11. OIDC state and nonce validation** ✅ — `internal/auth/oidc.go` validates both. Good.\n\n---\n\n## Recommended remediation priority\n\n1. **C1 + C2** — open redirect and NATS authz. Both are exploitable in realistic deployments. C1 is a one-line fix; C2 requires either docs + ACL guidance, or a token requirement in messages.\n2. **H1 + H2** — CORS and HttpOnly. Both are small code changes with significant defense-in-depth impact.\n3. **H3, M1, M2** — fail loud on missing SESSION_KEY, add HSTS, fix issuer check order.\n4. **M3, M4** — JWT lifetime/revocation policy and CSRF tokens. Larger design changes; defer unless threat model demands them.\n\n## Verification\n\nThis audit reads code only; nothing was executed. To validate findings after fixes:\n- C1: `curl -i -d 'username=...&password=...&redirect=https://evil.example.com/' http://localhost:8080/login` should not return a `Location: https://evil.example.com/` header.\n- H1: `curl -i -H 'Origin: https://evil.example.com' http://localhost:8080/frontend/...` — the response should not echo `Access-Control-Allow-Origin: https://evil.example.com` with credentials.\n- H2: `curl -i -d 'username=...&password=...' http://localhost:8080/login` — the `Set-Cookie: session=...` header should include `HttpOnly`.\n\n## Out of scope\n\n- Authorization correctness at the GraphQL resolver level (e.g. whether each mutation checks roles consistently).

To validate findings after fixes:\n- C1: `curl -i -d 'username=...&password=...&redirect=https://evil.example.com/' http://localhost:8080/login` should not return a `Location: https://evil.example.com/` header.\n- H1: `curl -i -H 'Origin: https://evil.example.com' http://localhost:8080/frontend/...` — the response should not echo `Access-Control-Allow-Origin: https://evil.example.com` with credentials.\n- H2: `curl -i -d 'username=...&password=...' http://localhost:8080/login` — the `Set-Cookie: session=...` header should include `HttpOnly`.\n\n## Out of scope\n\n- Authorization correctness at the GraphQL resolver level (e.g. whether each mutation checks roles consistently). The audit noted inconsistencies in `internal/graph/schema.resolvers.go` but did not enumerate them. Worth a follow-up review.\n- Job-archive backend (S3 credentials, file permissions).\n- Metricstore client (`internal/metricstoreclient`) auth to upstream `cc-metric-store`.\n- Frontend XSS audit (Svelte template injection surfaces).\n","isAgent":false,"filePath":"/Users/jan/.claude/plans/do-a-security-audit-gleaming-toucan.md"},"sourceToolAssistantUUID":"ab18ced2-7fc5-4517-9ef0-75850ffaa295","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"353978ad-68ce-4328-86fa-db08ca2d0670","isSidechain":false,"attachment":{"type":"plan_mode_exit","planFilePath":"/Users/jan/.claude/plans/do-a-security-audit-gleaming-toucan.md","planExists":true},"type":"attachment","uuid":"7b2ffd90-b2c5-4711-8cac-3c3d8240413f","timestamp":"2026-06-04T16:16:47.272Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"7b2ffd90-b2c5-4711-8cac-3c3d8240413f","isSidechain":false,"attachment":{"type":"auto_mode"},"type":"attachment","uuid":"7d69d087-4844-4919-b90c-027e1695c6d1","timestamp":"2026-06-04T16:16:47.272Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"type":"last-prompt","lastPrompt":"Do a security audit of the authentication in this application.","leafUuid":"7d69d087-4844-4919-b90c-027e1695c6d1","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4"} +{"type":"ai-title","aiTitle":"Security audit of authentication system","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4"} +{"type":"mode","mode":"normal","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4"} +{"type":"permission-mode","permissionMode":"auto","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4"} +{"type":"ai-title","aiTitle":"security-audit-cc-backend-auth","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4"} +{"type":"agent-name","agentName":"security-audit-cc-backend-auth","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4"} +{"parentUuid":"7d69d087-4844-4919-b90c-027e1695c6d1","isSidechain":false,"message":{"model":"claude-opus-4-7","id":"msg_011yMLNmZ3ZtpCwhMcwp43hR","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"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"}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":6158,"cache_read_input_tokens":85707,"output_tokens":834,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":6158,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":1,"output_tokens":834,"cache_read_input_tokens":85707,"cache_creation_input_tokens":6158,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":6158},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CbiX7NgYBdFaXQq7fnP53","type":"assistant","uuid":"f7444974-63d7-498f-99f1-21c7f6d52ae0","timestamp":"2026-06-04T16:16:52.269Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"f7444974-63d7-498f-99f1-21c7f6d52ae0","isSidechain":false,"message":{"model":"claude-opus-4-7","id":"msg_011yMLNmZ3ZtpCwhMcwp43hR","type":"message","role":"assistant","content":[{"type":"text","text":"Audit complete.

Exploitable as a phishing primitive.\n- **CRITICAL — NATS API has zero authentication** in `internal/api/nats.go:132-157`. Anyone with NATS publish rights can start/stop jobs and rewrite node state. The REST equivalents require `RoleAPI`; the NATS path bypasses that entirely.\n- **HIGH — CORS** in `cmd/cc-backend/server.go:131-136` uses `AllowedOrigins: [\"*\"]` with `AllowCredentials: true`. go-chi/cors echoes the request `Origin` back, exposing credentialed cross-origin reads.\n- **HIGH — Session cookies aren't `HttpOnly`** (`auth.go:315-327`). gorilla/sessions defaults to `false`; XSS → session theft.\n- **HIGH — `SESSION_KEY` fallback** silently invalidates all sessions on restart and breaks multi-replica deployments — a foot-gun that warns once and proceeds.\n- **MEDIUM** — no HSTS; JWT issuer is read from unvalidated claims to choose the verification key (jwtCookieSession.go:122-137); no JWT revocation; no CSRF tokens (relying only on SameSite=Lax).\n- **Good** — bcrypt hashing, LDAP/SQL injection-safe, generic auth errors, current JWT v5 lib, OIDC state+nonce validated, rate limiting present, frontend doesn't put JWTs in localStorage.\n\nThe two CRITICALs are the priorities.

tests pass. Summary of changes:\n\n**C1 — Open redirect** (`internal/auth/auth.go:393-398`): redirect parameter now validated as a relative path (no scheme, no host); non-relative values are warn-logged and dropped to `/`.\n\n**C2 — NATS auth gap** (`internal/api/nats.go:154-157` + `CLAUDE.md`): startup log upgraded to a loud `Warn` explicitly calling out the lack of authentication; added a `### Security Considerations` subsection in CLAUDE.md documenting that broker-level ACLs are mandatory. **Note:** this does not add code-level enforcement — implementing signed JWTs in line-protocol payloads would be a follow-up.\n\n**H1 — CORS** (`cmd/cc-backend/server.go:132`): `AllowCredentials: true` → `false`. Same-origin frontend (cookies) and JWT-bearer API consumers (Authorization header, not \"credentials\") both continue to work. Cross-origin credentialed exfiltration via session cookies is closed.\n\n**H2 — HttpOnly** (`internal/auth/auth.go:323`): `session.Options.HttpOnly = true` in `SaveSession`.\n\n**H3 — SESSION_KEY** (`internal/auth/auth.go:188-197`): missing `SESSION_KEY` now `Fatal` with an explicit message about persistence; ephemeral-random fallback removed. Test setups in `api_test.go` and `nats_test.go` updated to set the env var via `t.Setenv`.\n\n**M1 — HSTS** (`cmd/cc-backend/server.go:137-145`): new middleware emits `Strict-Transport-Security: max-age=31536000; includeSubDomains` whenever the request arrives via TLS (direct `r.TLS != nil` or `X-Forwarded-Proto: https` — same detection the existing Secure-cookie path uses).\n\n**M2 — JWT issuer check** (`internal/auth/jwtCookieSession.go:122-149`): replaced the unvalidated-issuer key-selection callback with: `ParseUnverified` to read the issuer claim, explicit dispatch (`TrustedIssuer` → cross-login key, empty → local key, anything else → reject), then verify with `WithValidMethods([EdDSA])`. The previous silent fallback — where compromising either key would let an attacker forge tokens claiming the other issuer — is gone.\n\nBreaking-change callouts for your release notes:\n- Operators upgrading from a deployment that ran without `SESSION_KEY` will now hit a startup fatal. Anyone who used `cc-backend -init` already has it in `.env`.\n- Any external integration relying on cross-origin requests *with cookies* will stop working; JWT-header consumers are unaffected."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":1154,"cache_read_input_tokens":121076,"output_tokens":1909,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1154,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":1,"output_tokens":1909,"cache_read_input_tokens":121076,"cache_creation_input_tokens":1154,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1154},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CbiXmH4WeGPXeSz1wZFoJ","type":"assistant","uuid":"fe9d8739-9ba6-477d-9518-5390e984a1cb","timestamp":"2026-06-04T16:25:47.672Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"fe9d8739-9ba6-477d-9518-5390e984a1cb","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":1,"hookInfos":[{"command":"entire hooks claude-code stop","durationMs":3772}],"hookErrors":[],"preventedContinuation":false,"stopReason":"","hasOutput":false,"level":"suggestion","timestamp":"2026-06-04T16:25:51.508Z","uuid":"a74fb322-eb09-4f3b-b1d9-fb0662552f06","toolUseID":"db8b88e4-566a-4dc7-8386-af5cd6b16105","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"a74fb322-eb09-4f3b-b1d9-fb0662552f06","isSidechain":false,"type":"system","subtype":"turn_duration","durationMs":399730,"messageCount":154,"timestamp":"2026-06-04T16:25:51.509Z","uuid":"caedd02d-32a0-421a-8f2e-2c974b0eabf8","isMeta":false,"userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"cbcbe1ec-fe11-4ef8-99db-848a3428c3e4","version":"2.1.152","gitBranch":"release/v1.5","slug":"do-a-security-audit-gleaming-toucan"} +{"parentUuid":"caedd02d-32a0-421a-8f2e-2c974b0eabf8","isSidechain":false,"type":"system","subtype":"away_summary","content":"Security audit of cc-backend auth complete and priority 1-3 fixes applied (open redirect, NATS warning, CORS, HttpOnly, SESSION_KEY fatal, HSTS, JWT issuer check); all tests pass.
