CVE-2026-65054Network attack vector

Private metadata disclosure via unchecked playlist additions

Published Jul 21, 2026 · Updated Jul 21, 2026

Incorrect authorization in MediaCMS 8.2.0 allows remote authenticated users to read other users' private media metadata via playlists. The playlist update API accepts an arbitrary media token without checking state or ownership, and the owner-only playlist detail branch returns the referenced item's metadata without filtering it. Regular user access and knowledge of a media token are required; exposure is limited to metadata because a separate nginx authorization layer protects the media stream.
