CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2026-34362 impacting wwbn avideo. Evaluated with CVSS Base Score of 5.4 (MEDIUM).

Original NVD Description

Source: NIST NVD
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.
