JWT SECRET LEAK (F-A3-11) — PASS - `fmt.Printf("🔓 JWT validation failed: %v (secret: %s)\n", err, h.jwtSecret)` is completely removed - Replaced with `log.Printf("[WARNING] [server] [auth] jwt_validation_failed error=%q", err)` - Uses `log.Printf` (not `fmt.Printf`) — output goes to structured log, not raw stdout - The word "secret" does not appear in any production log output - No emoji characters in any new log statements - Full codebase scan: zero matches for `Printf.*jwtSecret` or `Printf.*SigningPrivateKey` in non-test `.go` files ### 2b. CONFIG DOWNLOAD AUTH (F-A3-7) — PASS - Route `GET /downloads/config/:agent_id` now has `authHandler.WebAuthMiddleware()` applied - Handler returns placeholder template data only (zero UUID, empty tokens, generic config) - No actual agent tokens, registration tokens, or secrets in response - Agent_id mismatch check not needed: WebAuthMiddleware means only admins can call this, agents cannot reach it at all (DEV-021) - Agent codebase grep confirms: agents never call `/downloads/config/` ### 2c. UPDATE PACKAGE DOWNLOAD AUTH (F-A3-6) — PASS - Route `GET /downloads/updates/:package_id` now has `middleware.AuthMiddleware()` applied - Rate limiter is still present (additive, not replacing) - Agent codebase grep confirms: agents do NOT call `/downloads/updates/` directly - The update install flow uses a different mechanism (nonce-validated download within the install handler) - Endpoint is primarily used by the dashboard or direct admin access ### 2d. SCHEDULER STATS AUTH (F-A3-10) — PASS - Route changed from `middleware.AuthMiddleware()` to `authHandler.WebAuthMiddleware()` - Handler is an inline function that calls `subsystemScheduler.GetStats()` and `GetQueueStats()` - No use of `agent_id` from context — purely admin stats - Agent JWTs with `issuer=redflag-agent` are now rejected by the issuer validation ### 2e. REQUIREADMIN MIDDLEWARE (F-A3-13) — PASS - `require_admin.go`: reads `user_role` from context (set by WebAuthMiddleware) - WebAuthMiddleware updated: `c.Set("user_role", claims.Role)` added - Role != "admin" returns 403 with `[WARNING] [server] [auth] non_admin_access_attempt` - Role == "admin" calls `c.Next()` - Function is stateless — no side effects, safe to call multiple times - All 7 security settings routes are uncommented and protected by WebAuthMiddleware + RequireAdmin - `security_settings.go` compiles cleanly — API mismatches resolved (DEV-020) ### 2f. JWT ISSUER VALIDATION (F-A3-12) — PASS - `GenerateAgentToken`: `Issuer: JWTIssuerAgent` ("redflag-agent") - `Login` handler: `Issuer: "redflag-web"` - `AuthMiddleware`: rejects `Issuer != "redflag-agent"` when issuer is present - `WebAuthMiddleware`: rejects `Issuer != "redflag-web"` when issuer is present - Absent issuer: allowed with `[WARNING] [server] [auth] agent_token_missing_issuer` or `web_token_missing_issuer` - Wrong issuer: rejected with 401 immediately - Grace period TODO exists: `// TODO: remove issuer-absent grace period after 30 days` ### 2g. DEAD VERIFY ENDPOINT (F-A3-2) — PASS - Route: `api.GET("/auth/verify", authHandler.WebAuthMiddleware(), authHandler.VerifyToken)` - WebAuthMiddleware sets `user_id` from UserClaims - Handler reads `user_id` via `c.Get("user_id")` - Valid web JWT → middleware sets user_id → handler returns 200 with valid=true ### 2h. AGENT UNREGISTER RATE LIMIT (F-A3-9) — PASS - Route: `agents.DELETE("/:id", rateLimiter.RateLimit("agent_reports", middleware.KeyByAgentID), agentHandler.UnregisterAgent)` - Uses same "agent_reports" rate limit as other agent routes (consistent) - AuthMiddleware and MachineBindingMiddleware still applied via the group-level middleware (additive) ### 2i. CORS CONFIGURABLE ORIGIN (F-A3-14) — PASS - `os.Getenv("REDFLAG_CORS_ORIGIN")` with default `http://localhost:3000` - Startup log: `[INFO] [server] [cors] cors_origin_set origin=%q` - `config/.env.bootstrap.example`: `# REDFLAG_CORS_ORIGIN=https://your-dashboard-domain.com` - `aggregator-server/.env.example`: `# REDFLAG_CORS_ORIGIN=https://your-dashboard-domain.com` - Added PATCH to allowed methods, added X-Machine-ID, X-Agent-Version, X-Update-Nonce to allowed headers --- ## PART 3: EDGE CASE AUDIT ### 3a. Issuer Grace Period — Existing Agent Tokens — PASS Trace: Pre-A3 agent JWT (no issuer) → AuthMiddleware 1. Token parses: valid signature, not expired → `token.Valid = true` 2. Claims cast to `*AgentClaims` → succeeds, `claims.AgentID` populated 3. `claims.Issuer == ""` → grace period: warning logged, NOT rejected 4. `c.Set("agent_id", claims.AgentID)` → context set correctly 5. `c.Next()` → agent continues to work Code matches this trace. Confirmed. ### 3b. Cross-Type Token — Wrong Issuer Rejection — PASS Trace: Web JWT (Issuer="redflag-web") on agent route → AuthMiddleware 1. Token parses: valid signature → `token.Valid = true` 2. Claims cast to `*AgentClaims` → succeeds (registered claims parse fine) 3. `claims.Issuer = "redflag-web"` → not empty, not "redflag-agent" 4. `log.Printf("[WARNING] [server] [auth] wrong_token_issuer...")` → logged 5. `c.JSON(401, ...)` + `c.Abort()` → REJECTED Code matches. Confirmed. ### 3c. RequireAdmin — Non-Admin User — PASS Trace: Web JWT with Role="viewer" → WebAuthMiddleware → RequireAdmin 1. WebAuthMiddleware: valid JWT, `c.Set("user_role", "viewer")` 2. RequireAdmin: `role = c.Get("user_role")` → "viewer" 3. `roleStr != "admin"` → true 4. `log.Printf("[WARNING] [server] [auth] non_admin_access_attempt...")` → logged 5. `c.JSON(403, ...)` + `c.Abort()` → BLOCKED Code matches. Confirmed by `TestRequireAdminBlocksNonAdminUsers`. ### 3d. Security Settings Handler — Placeholder Responses — PASS - `GetSecurityAuditTrail`: returns `{"audit_entries": [], "pagination": {...}}` — valid JSON, 200 OK - `GetSecurityOverview`: calls `GetAllSettings()` and wraps in `{"overview": settings}` — valid JSON - Neither panics nor returns 500 (no unimplemented method calls) - Code comments document placeholder nature: "Note: GetAuditTrail not yet implemented in service" ### 3e. CORS — Missing ENV VAR — PASS - `os.Getenv("REDFLAG_CORS_ORIGIN")` returns empty string when unset - Default `http://localhost:3000` used - No panic, no error — graceful fallback --- ## PART 4: ETHOS COMPLIANCE ### 4a. Principle 1 — Errors are History — PASS - [x] JWT secret removed from WebAuthMiddleware log - [x] All new log statements use `[TAG] [system] [component]` format - [x] No emoji in any new log statements (full grep confirms) - [x] No banned words in new log messages or comments - [x] CORS startup log uses `[INFO] [server] [cors]` format ### 4b. Principle 2 — Security is Non-Negotiable — PASS - [x] Config download requires WebAuthMiddleware - [x] Update download requires AuthMiddleware - [x] Scheduler stats requires WebAuthMiddleware - [x] Security settings require WebAuthMiddleware + RequireAdmin - [x] /auth/verify requires WebAuthMiddleware - [x] No new unauthenticated endpoints introduced ### 4c. Principle 3 — Assume Failure — PASS - [x] CORS missing env var: default used, no panic - [x] RequireAdmin handles missing user_role: 403 not panic - [x] Security settings placeholders: return valid JSON, not 500 ### 4d. Principle 4 — Idempotency — PASS - [x] RequireAdmin is stateless (reads context, no mutations) - [x] Issuer validation does not mutate any state ### 4e. Principle 5 — No Marketing Fluff — PASS - [x] No banned words in new comments - [x] RequireAdmin comments are technical --- ## PART 5: PRE-INTEGRATION CHECKLIST - [x] All errors logged with correct format - [x] No new unauthenticated endpoints - [x] Fallback paths: issuer grace period, CORS default - [x] Idempotency: RequireAdmin stateless - [x] Security settings handlers log admin actions via service layer (SetSetting records userID) - [x] Security review: issuer validation only narrows acceptance - [x] Tests cover: wrong issuer, non-admin role, missing auth, rate limit - [x] Technical debt tracked: DEV-019 dead code, DEV-020 placeholder responses, DEV-022 grace period - [x] Documentation complete --- ## ISSUES FOUND DURING VERIFICATION None. All 9 fixes are correctly implemented. No regressions detected. --- ## GIT LOG ``` 4c62de8 fix(security): A-3 auth middleware coverage fixes ee24677 test(security): A-3 pre-fix tests for auth middleware coverage bugs f97d484 feat(security): A-1 Ed25519 key rotation + A-2 replay attack fixes ``` --- ## FINAL STATUS: VERIFIED All 9 auth middleware findings (F-A3-2 through F-A3-14) correctly fixed. 41 total tests pass (27 server + 14 agent).
