## Description

The Broadcast Live Video – Live Streaming : WebRTC, HLS, RTSP, RTMP plugin for WordPress is vulnerable to unauthorized access via the 'h5vls_app' AJAX action in all versions up to, and including, 7.3.13. This is due to a missing check that the validated session belongs to the room ID supplied in the request. This makes it possible for unauthenticated attackers to take a session obtained for one room they may access and use it against another room, getting around the room access checks (access lists and members-only viewing) that are only enforced when the room page is rendered.
