From 4c62de8d8be78bbff3e02b66db0728604c95c021 Mon Sep 17 00:00:00 2001 From: jpetree331 Date: Sat, 28 Mar 2026 22:17:40 -0400 Subject: [PATCH] fix(security): A-3 auth middleware coverage fixes Fixes 9 auth middleware findings from the A-3 recon audit. F-A3-11 CRITICAL: Removed JWT secret from WebAuthMiddleware log output. Replaced emoji-prefixed fmt.Printf with ETHOS-compliant log.Printf. No secret values in any log output. F-A3-7 CRITICAL: Config download now requires WebAuthMiddleware. GET /downloads/config/:agent_id is admin-only (agents never call it). F-A3-6 HIGH: Update package download now requires AuthMiddleware. GET /downloads/updates/:package_id requires valid agent JWT. F-A3-10 HIGH: Scheduler stats changed from AuthMiddleware to WebAuthMiddleware. Agent JWTs can no longer view scheduler internals. F-A3-13 LOW: RequireAdmin() middleware implemented. 7 security settings routes re-enabled (GET/PUT/POST under /security/settings). security_settings.go.broken renamed to .go, API mismatches fixed. F-A3-12 MEDIUM: JWT issuer claims added for token type separation. Agent tokens: issuer=redflag-agent, Web tokens: issuer=redflag-web. AuthMiddleware rejects tokens with wrong issuer. Grace period: tokens with no issuer still accepted (backward compat). F-A3-2 MEDIUM: /auth/verify now has WebAuthMiddleware applied. Endpoint returns 200 with valid=true for valid admin tokens. F-A3-9 MEDIUM: Agent self-unregister (DELETE /:id) now rate-limited using the same agent_reports rate limiter as other agent routes. F-A3-14 LOW: CORS origin configurable via REDFLAG_CORS_ORIGIN env var. Defaults to http://localhost:3000 for development. Added PATCH method and agent-specific headers to CORS config. All 27 server tests pass. All 14 agent tests pass. No regressions. See docs/A3_Fix_Implementation.md and docs/Deviations_Report.md (DEV-020 through DEV-022).

Dashboard users need to be logged in. + +--- + +## DEV-022: Issuer grace period for backward compat (A-3) + +**Issue:** Adding issuer validation to JWT middleware would immediately invalidate all existing deployed agent tokens (which have no issuer claim). + +**Solution:** Tokens with empty/absent issuer are allowed through with a logged warning. Tokens with a WRONG issuer (e.g., `redflag-web` on agent middleware) are rejected immediately. This provides a migration path: new tokens have issuers, old tokens work during the grace period. + +**TODO:** Remove issuer-absent grace period after 30 days from deployment. At that point, all deployed agents will have rotated their tokens (24h expiry). + +**Impact:** Cross-type token confusion is blocked for new tokens. Old tokens degrade gracefully.
