Description

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginImport.json.php` endpoint allows admin users to upload and install plugin ZIP files containing executable PHP code, but lacks any CSRF protection. Combined with the application explicitly setting `session.cookie_samesite = 'None'` for HTTPS connections, an unauthenticated attacker can craft a page that, when visited by an authenticated admin, silently uploads a malicious plugin containing a PHP webshell, achieving Remote Code Execution on the server. Commit d1bc1695edd9ad4468a48cea0df6cd943a2635f3 contains a patch.
