Session binding was bypassable: if the X-Session-Id header was absent,
validate_token skipped the check entirely, allowing a stolen JWT to be
used without the originating session.
Server-side: reject 401 early in Flask middleware and daemon WebSocket
handler when X-Session-Id is missing, before calling validate_token.
Updated validate_token to always enforce session_id matching for access
tokens (refresh tokens are unaffected as they carry no session_id claim).
Frontend: removed dead if (stored.session_id) guards in api.js since
the header is now always required. Added X-Session-Id to logout request
headers and always store session_id on login/refresh.
- Rate limiter tracks failures only; success resets counter
- Record failures/successes after password verification, not before
- WebAuthn rp_id/origin resolved dynamically from request domain
- Management domains auto-discovered from nginx backend config
- All WebAuthn operations validate domain against management list
- Add GET /api/auth/webauthn/capable endpoint for frontend checks
- Frontend checkWebAuthnCapable() function for domain-gated UI
- Timing side-channel fix: pre-compute dummy hash at module load
- Builtin admin seeded with random password (logged at WARNING)
- Logout handler returns consistent response shape
Drop ?v=N version pins from all JS imports and HTML <link>/<script> tags.
Cache invalidation is now handled solely by server-side cache-control headers.
Update docs and AGENTS.md accordingly.
Aligns user and permissions storage with the existing sessionStorage-based
token model. Eliminates the dual-write pattern and stale cross-session data.
