CVE-2026-33479

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the Gallery plugin's saveSort.json.php endpoint passes unsanitized user input from $_REQUEST['sections'] array values directly into PHP's eval() function. While the endpoint is gated behind User::isAdmin(), it has no CSRF token validation. Combined with AVideo's explicit SameSite=None session cookie configuration, an attacker can exploit this via cross-site request forgery to achieve unauthenticated remote code execution — requiring only that an admin visits an attacker-controlled page. Commit 087dab8841f8bdb54be184105ef19b47c5698fcb contains a patch.
