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.
CVE-2023-48702
This high-severity CVE scores 7.2 under NVD CVSS v3. EPSS exploit probability: 1.2%, top 35% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
