AVideo's Video Moderator Privilege Escalation via Ownership Transfer Enables Arbitrary Video Deletion
Description d'origine
La description telle que publiée par la source (souvent en anglais).
WWBN AVideo is an open source video platform. In versions up to and including 26.0, a user with the "Videos Moderator" permission can escalate privileges to perform full video management operations — including ownership transfer and deletion of any video — despite the permission being documented as only allowing video publicity changes (Active, Inactive, Unlisted). The root cause is that Permissions::canModerateVideos() is used as an authorization gate for full video editing in videoAddNew.json.php, while videoDelete.json.php only checks ownership, creating an asymmetric authorization boundary exploitable via a two-step ownership-transfer-then-delete chain. Commit 838e16818c793779406ecbf34ebaeba9830e33f8 contains a patch.
