Jellyfin through 12.4 contains an authorization bypass vulnerability in SuggestionsController.GetSuggestions that allows authenticated non-administrator users to bypass library and parental restrictions by omitting the userId parameter. Attackers can repeatedly call GET /Items/Suggestions without userId to enumerate restricted items, including IDs and server filesystem paths, and then stream them.
