## Description

The Broadcast Live Video – Live Streaming : WebRTC, HLS, RTSP, RTMP plugin for WordPress is vulnerable to Sensitive Information Exposure via the videochat room user list returned by the 'h5vls_app' AJAX action in all versions up to, and including, 7.3.13. This is due to appRoomUsers() returning each participant's full session meta array, which includes the secret 'h5vls_session_key', together with the session ID. This makes it possible for unauthenticated attackers who open a guest videochat session in a room to retrieve the session secrets and internal session metadata of the other participants in that room.
