Unauthorized comments via missing video-access check
Published Sep 12, 2026 · Updated Sep 12, 2026
Missing authorization in WWBN AVideo allows remote authenticated users to add comments to videos they cannot access. The commentAddNew.json.php endpoint saves a submitted comment after checking comment permission but never verifies that the session can view the referenced password-protected or group-restricted video. A valid session with comment permission is required, and exploitation writes attacker-controlled comments without disclosing the protected video.
