What it is

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate video access permissions in the commentAddNew.json.php endpoint, allowing authenticated users to post comments on password-protected and group-restricted videos. Attackers can submit POST requests with a valid session to add comments to videos they cannot watch, bypassing password and group access controls.
