Vulnerability · CVE-2025-31499
Jellyfin is an open source self hosted media server.
Published Apr 15, 2025 · corrected/updated Apr 16, 2025 · jellyfin jellyfin · evidence confidence high
Jellyfin is an open source self hosted media server. Versions before 10.10.7 are vulnerable to argument injection in FFmpeg. This can be leveraged to possibly achieve remote code execution by anyone with credentials to a low-privileged user. This vulnerability was previously reported in CVE-2023-49096 and patched in version 10.8.13, but the patch can be bypassed. The original fix sanitizes some parameters to make injection impossible, but certain unsanitized parameters can still be used for argument injection. The same unauthenticated endpoints are vulnerable: /Videos/ /stream and /Videos/ /st
