Lifecycle Timeline
4Description
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the AVideo endpoint objects/pluginSwitch.json.php allows administrators to enable or disable any installed plugin. The endpoint checks for an active admin session but does not validate a CSRF token. Additionally, the plugins database table is explicitly listed in ignoreTableSecurityCheck(), which means the ORM-level Referer/Origin domain validation in ObjectYPT::save() is also bypassed. Combined with SameSite=None on session cookies, an attacker can disable critical security plugins (such as LoginControl for 2FA, subscription enforcement, or access control plugins) by luring an admin to a malicious page. At time of publication, there are no publicly available patches.
Analysis
CSRF vulnerability in WWBN AVideo 26.0 and prior allows unauthenticated attackers to disable critical security plugins on admin accounts via malicious web pages, exploiting missing CSRF token validation combined with SameSite=None session cookies and ORM-level security bypass. An attacker can trick an authenticated administrator into visiting a crafted webpage that silently disables plugins such as LoginControl (2FA), subscription enforcement, or access control mechanisms, compromising the platform's security posture without the admin's knowledge or consent.
