December 13, 2023
Jellyfin is a system for managing and streaming media. Prior to version 10.8.13, the "/System/MediaEncoder/Path" endpoint executes an arbitrary file using "ProcessStartInfo" via the "ValidateVersion" function. A malicious administrator can setup a network share and supply a UNC path to "/System/MediaEncoder/Path" which points to an executable on the network share, causing Jellyfin server to run the executable in the local context. The endpoint was removed in version 10.8.13.
