Title
MediaCMS Private Media Metadata Disclosure via Playlist Ownership Loophole
Summary
MediaCMS 8.2.0 contains an information disclosure vulnerability that allows authenticated users to expose private media metadata belonging to other users by adding arbitrary media tokens to their own playlist without access control checks. Attackers can issue a PUT request to the playlist API endpoint with a known media token to bypass state and ownership validation, then retrieve the playlist to read private media fields including title, description, view count, like count, file size, author username, and encoding status through the unfiltered playlist owner branch in the playlist detail view.
