CVE-2026-33650 · AVideo's Video Moderator Privilege Escalation via Ownership Transfer Enables Arbitrary Video Deletion

Здесь приведены факты из открытых источников об уязвимостях. Перед обновлением ознакомьтесь с исходным сообщением.

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.
