Description
UNIT3D through 9.2.0 contains a missing authorization vulnerability in PlaylistZipController::show that allows authenticated users to download other members' private playlists. Attackers can enumerate sequential playlist ids at the /playlist-zips/{playlist} endpoint to obtain zips of all torrents, disclosing private collection membership.
