WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `verifyTokenSocket()` function in `plugin/YPTSocket/functions.php` has its token timeout validation commented out, causing WebSocket tokens to never expire despite being generated with a 12-hour timeout. This allows captured or legitimately obtained tokens to provide permanent WebSocket access, even after user accounts are deleted, banned, or demoted from admin. Admin tokens grant access to real-time connection data for all online users including IP addresses, browser info, and page locations. Commit 5d5237121bf82c24e9e0fdd5bc1699f1157783c5 fixes the issue.

WebSocket token validation bypass in WWBN AVideo versions up to 26.0 allows authenticated attackers to retain permanent real-time access to sensitive connection metadata after account revocation. The verifyTokenSocket() function fails to enforce token expiration despite generating 12-hour timeouts, enabling captured tokens to grant indefinite access to admin-level data including IP addresses, browser fingerprints, and user page locations. …
