WWBN AVideo Missing Authorization via resendRestreamer.json.php
Description

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate ownership of live_restreams_id in resendRestreamer.json.php, allowing authenticated users with canStream to access other users' restream destinations. Attackers can broadcast their live stream to victim-configured restream destinations by supplying arbitrary live_restreams_id values, hijacking YouTube, Facebook, or Twitch streams using victim stream keys.
