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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":7.2},"cwes":["CWE-77"],"references":["https://github.com/jellyfin/jellyfin/commit/83d2c69516471e2db72d9273c6a04247d0f37c86","https://github.com/jellyfin/jellyfin/security/advisories/GHSA-rr9h-w522-cvmr","https://securitylab.github.com/advisories/GHSL-2023-028_jellyfin/","https://github.com/jellyfin/jellyfin/commit/83d2c69516471e2db72d9273c6a04247d0f37c86","https://github.com/jellyfin/jellyfin/security/advisories/GHSA-rr9h-w522-cvmr"],"products":["jellyfin:jellyfin"],"source":"nvd","synced_at":"2026-10-19T21:42:34.585441961+00:00"},"epss":{"cve":"CVE-2023-48702","score":0.01196,"percentile":0.68103,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
