What it is

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate video access permissions in the like.json.php endpoint, allowing logged-in users to record likes on password-protected and group-restricted videos. Attackers can submit like requests for videos they cannot watch to increment like counters and bypass access controls.
