Addresses CWE-598: long-lived JWTs were exposed in WebSocket URLs, file
download links, and Immich asset proxy URLs, leaking into server logs,
browser history, and Referer headers.
- Add ephemeralTokens service: in-memory single-use tokens with per-purpose
TTLs (ws=30s, download/immich=60s), max 10k entries, periodic cleanup
- Add POST /api/auth/ws-token and POST /api/auth/resource-token endpoints
- WebSocket auth now consumes an ephemeral token instead of verifying the JWT
directly from the URL; client fetches a fresh token before each connect
- File download ?token= query param now accepts ephemeral tokens; Bearer
header path continues to accept JWTs for programmatic access
- Immich asset proxy replaces authFromQuery JWT injection with ephemeral token
consumption
- Client: new getAuthUrl() utility, AuthedImg/ImmichImg components, and async
onClick handlers replace the synchronous authUrl() pattern throughout
FileManager, PlaceInspector, and MemoriesPanel
- Add OIDC_DISCOVERY_URL env var and oidc_discovery_url DB setting to allow
overriding the auto-constructed discovery endpoint (required for Authentik
and similar providers); exposed in the admin UI and .env.example
