CVE-2026-119596 Details
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.
A missing authorization vulnerability has been identified in UNIT3D versions through 9.2.0, specifically in the PlaylistZipController::show method. This vulnerability allows authenticated users to download private playlists of other members. The issue arises because the endpoint responsible for zipping and streaming playlist contents does not verify if a playlist is private or if the requesting user is authorized to access it. As a result, any authenticated user can enumerate playlist IDs and download the associated torrent files, thereby disclosing private collection memberships.
The vulnerability has been addressed in a recent commit by adding the necessary authorization checks to the PlaylistZipController. Users should update to the latest version of UNIT3D to mitigate this vulnerability.
