Description
XBackBone through 3.8.2 contains a missing authorization vulnerability that allows authenticated users to change other users' upload share codes via the POST /upload/{id}/vanity route. Attackers can supply sequential upload ids to MediaController::createVanity() to break existing share links and hijack the freed codes with their own uploads.
