Vulnerability details
The vulnerability allows a remote attacker to disclose restricted live-stream viewing credentials, stream links, server identifiers, and private programme schedules.
The vulnerability exists due to missing authentication and playlist visibility checks in AVideo's plugin/PlayLists/epg.json.php endpoint when serializing electronic programme guide objects containing live-stream keys.
