Title

Jellyfin Possible Remote Code Execution via custom FFmpeg binary

Summary

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.

Severity

7.2 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
