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.
