WWBN AVideo is an open source video platform. In versions 29.0 and below, the CORS origin validation fix in commit `986e64aad` is incomplete. Two separate code paths still reflect arbitrary `Origin` headers with credentials allowed for all `/api/*` endpoints: (1) `plugin/API/router.php` lines 4-8 unconditionally reflect any origin before application code runs, and (2) `allowOrigin(true)` called by `get.json.php` and `set.json.php` reflects any origin with `Access-Control-Allow-Credentials: true`. An attacker can make cross-origin credentialed requests to any API endpoint and read authenticated responses containing user PII, email, admin status, and session-sensitive data. Commit 5e2b897ccac61eb6daca2dee4a6be3c4c2d93e13 contains a fix.
