CVE-2026-41057: AVideo has CORS Origin Reflection Bypass via plugin/API/router.php and allowOrigin(true) that Exposes Authenticated API Responses

Published Apr 21, 2026

Updated

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.
