Description
Jellyfin through 12.4 contains an information disclosure vulnerability in PlaylistsController.GetPlaylist that allows authenticated users to read hidden item IDs by requesting public or shared playlists. Restricted or parental-controlled users can obtain GUIDs of inaccessible library items from unfiltered playlist ItemIds and then stream that hidden media.
