Technical details
A missing authorization vulnerability in the Live plugin's restream endpoints allows authenticated users to supply arbitrary live_transmitions_history_id values to obtain other users' stream keys and HLS URLs. The verifyTokenForAction.json.php endpoint fails to verify that the authenticated user owns the requested stream, allowing attackers to redeem action tokens and gain access to victims' streaming credentials.
