Restream hijacking via unchecked ownership
Published Sep 10, 2026 · Updated Sep 10, 2026
Missing authorization in WWBN AVideo allows remote authenticated users with streaming permission to hijack restream destinations. getRestream.json.php mints an action token for a requested restream without confirming that the caller owns it, and getLiveKey.json.php exchanges that token for the stored stream key. Access requires canStream permission; exploitation discloses another user's destination credential and enables unauthorized publishing to that destination.
