Add require_session parameter to validate_token to enforce session_id
matching for refresh operations. Attacker with stolen refresh token can
no longer bypass session binding by omitting session_id from request.
Also adds backend guard against deleting builtin admin user (was only
blocked at Flask blueprint layer), and removes unused _ALL_RW variable.
- Add session_id to refresh tokens and enforce it during validation,
preventing stolen refresh tokens from being usable without the
originating browser session
- Set router.isAuthenticated via auth:login event after successful
login (previously only set at page load)
- Add console.warn logging to WS message parse/handler errors
- Improve _refreshPromise error handling in token refresh flow
- Document rate limiter in-memory limitation and CSP connect-src
same-origin requirement
- Add 3 tests for session-bound refresh token validation
- Make session_id parameter optional in validate_token — only enforced when
provided, allowing WebSocket auth which cannot carry custom headers
- Remove decode_token round-trip from daemon WS handler
- Override WebAuthn registration username from JWT user_ctx to prevent users
from registering credentials under another user's account
- Frontend no longer sends username for WebAuthn registration
- Redirect to login on 401 after token refresh fails for POST requests
- Remove redundant auth session check from login page load
- Add tests for session_id semantics and WebAuthn ownership guard
Browsers cannot send custom X-Session-Id header on WebSocket connections,
so decode the token payload to extract session_id. Add WebAuthn
success/failure recording to support rate limiter counter resets.
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.
The blacklist table grew indefinitely since cleanup only ran on
password changes and user deletions. Now each blacklist_token()
call has a 2% chance of triggering blacklist_expired() to prune
expired entries. Redundant cleanup calls in update_password()
and delete_user() are removed.
- 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
- Pass client IP (X-Real-IP header) through Flask to daemon for both
password login and WebAuthn authenticate-finish endpoints
- Rate limiter now checks both IP and username buckets: IP layer catches
enumeration/brute-force attacks across multiple usernames; username
layer protects against single-account targeting from multiple IPs
- Add _wsRefreshing flag to prevent double-scheduling reconnect when
onclose fires during token refresh; simplify async IIFE to .then()/.catch()
- Reset _wsRefreshing on websocket onopen for safety
Apply ruff line-wrapping formatting to docs and test files.
Clarify auth middleware: extract user_permissions once before
subsystem check, removing conditional variable scoping.
