Summary
WWBN AVideo through 29.7.1 contains a missing authorization vulnerability in Live plugin restream endpoints that allows authenticated streamers to obtain other users' stream keys by supplying arbitrary live_transmitions_history_id values. Attackers can redeem the issued action tokens at verifyTokenForAction.json.php to retrieve victims' HLS URLs and stream keys, then publish as the victim or restream private or pay-per-view lives.
