CVE-2026-33716

9.4 CRITICAL 0.5% exploit odds Fix listed Auth & access Web app

What it is

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.
