CVE-2026-34245: AVideo: Missing Authorization in Playlist Schedule Creation Allows Cross-User Broadcast Hijacking

The plugin/PlayLists/View/Playlists_schedules/add.json.php endpoint allows any authenticated user with streaming permission to create or modify broadcast schedules targeting any playlist on the platform, regardless of ownership. When the schedule executes, the rebroadcast runs under the victim playlist owner’s identity, allowing content hijacking and stream disruption.
