Description
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate playlist ownership in the Playlists_schedules/list.json.php and Live/calendar.json.php endpoints, allowing authenticated and unauthenticated users to read private playlist schedule metadata. Attackers with canStream privileges or no authentication can retrieve schedule names, descriptions, timestamps, and playlist identifiers by querying these endpoints without ownership checks.
