CVE-2026-33716 Details
Description
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the standalone live stream control endpoint at `plugin/Live/standAloneFiles/control.json.php` accepts a user-supplied `streamerURL` parameter that overrides where the server sends token verification requests. An attacker can redirect token verification to a server they control that always returns `{"error": false}`, completely bypassing authentication. This grants unauthenticated control over any live stream on the platform, including dropping active publishers, starting/stopping recordings, and probing stream existence. Commit 388fcd57dbd16f6cb3ebcdf1d08cf2b929941128 contains a patch.
A vulnerability in WWBN AVideo versions through 26.0 allows unauthenticated control of live streams by exploiting a token verification bypass. The issue arises in the standalone live stream control endpoint 'plugin/Live/standAloneFiles/control.json.php', where the 'streamerURL' parameter can be manipulated to redirect token verification requests to an attacker-controlled server. This server can be made to respond in a way that bypasses authentication, granting unauthorized access to live stream controls such as dropping publishers, starting or stopping recordings, and checking the existence of streams. The vulnerability also introduces a server-side request forgery (SSRF) risk, as the application makes outbound HTTP requests to the specified 'streamerURL' without proper validation.
Users are advised to update to version 28.0 or later, where this vulnerability has been addressed.
