WWBN AVideo is an open source video platform. In versions 29.0 and prior, the endpoint plugin/Live/view/Live_restreams/list.json.php contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated user with streaming permission to retrieve other users' live restream configurations, including third-party platform stream keys and OAuth tokens (access_token, refresh_token) for services like YouTube Live, Facebook Live, and Twitch. Commit d5992fff2811df4adad1d9fc7d0a5837b882aed7 fixes the issue.
