CVE-2026-33649

Summary

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the plugin/Permissions/setPermission.json.php endpoint accepts GET parameters for a state-changing operation that modifies user group permissions. The endpoint has no CSRF token validation, and the application explicitly sets session.cookie_samesite=None on session cookies. This allows an unauthenticated attacker to craft a page with <img> tags that, when visited by an admin, silently grant arbitrary permissions to the attacker's user group — escalating the attacker to near-admin access. As of time of publication, no known patched versions are available.
