WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate that logged-in users can access live schedules before creating reminders via remindMe.json.php. Authenticated attackers can create scheduler reminders for private live schedules they cannot view and learn the private schedule title from the generated email job.

The generated email job leaks the private schedule's title back to the attacker, constituting an information disclosure via IDOR (CWE-639). …
