AVideo's IDOR in uploadPoster.php Allows Any Authenticated User to Overwrite Scheduled Live Stream Posters and Trigger False Socket Notifications
Original description
The description as published by the source.
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the plugin/Live/uploadPoster.php endpoint allows any authenticated user to overwrite the poster image for any scheduled live stream by supplying an arbitrary live_schedule_id. The endpoint only checks User::isLogged() but never verifies that the authenticated user owns the targeted schedule. After overwriting the poster, the endpoint broadcasts a socketLiveOFFCallback notification containing the victim's broadcast key and user ID to all connected WebSocket clients. Commit 5fcb3bdf59f26d65e203cfbc8a685356ba300b60 fixes the issue.
