HIGH
- async handlers: Express 4 does not catch rejected promises and Node 22
exits on unhandled rejections — a malformed body ({} to /cropper/dequeue
etc.) could hang a request or kill the process. Every cropper route is
now wrapped (throw → 500 via next), request bodies are validated up
front (400), and JSON.parse of queue items is guarded. Server-wide
error middleware added, honouring err.status (413 for oversized bodies).
- error pages HTML-escape all interpolated values — the login failure page
rendered upstream (portal) error text raw.
MEDIUM
- outbound calls carry AbortSignal timeouts (5s OpenFGA verify, 15s
cropper upstreams) — a hung upstream can no longer pin a request.
- body limits scoped: /cropper gets 50mb (picture data URLs), everything
else 1mb (previously 50mb globally, memory-DoS surface pre-auth).
- cropper save validates the client-supplied domain against the catalog;
picture fetches validate the Minio object key (id-domains/ prefix, no ..).
LOW
- static assets served before the session middleware (no PocketBase load
per asset); landing header builds DOM nodes with textContent instead of
innerHTML; picture load checks upstream ok.
