CVE-2026-35032
Jellyfin: Potential SSRF + Arbitrary file read via LiveTV M3U tuner
Description
Jellyfin is an open source self hosted media server. Versions prior to 10.11.7 contain a vulnerability chain in the LiveTV M3U tuner endpoint (POST /LiveTv/TunerHosts), where the tuner URL is not validated, allowing local file read via non-HTTP paths and Server-Side Request Forgery (SSRF) via HTTP URLs. This is exploitable by any authenticated user because the EnableLiveTvManagement permission defaults to true for all new users. An attacker can chain these vulnerabilities by adding an M3U tuner pointing to an attacker-controlled server, serving a crafted M3U with a channel pointing to the Jellyfin database, exfiltrating the database to extract admin session tokens, and escalating to admin privileges. This issue has been fixed in version 10.11.7. If users are unable to upgrade immediately, they can disable Live TV Management privileges for all users.

Action Type Old Value New Value Added Translation Title: Jellyfin, Description: Jellyfin es un servidor multimedia de código abierto autoalojado. Las versiones anteriores a la 10.11.7 contienen una cadena de vulnerabilidades en el punto final del sintonizador M3U de LiveTV (POST /LiveTv/TunerHosts), donde la URL del sintonizador no se valida, permitiendo la lectura de archivos locales a través de rutas que no son HTTP y la falsificación de petición del lado del servidor (SSRF) a través de URL HTTP. Esto es explotable por cualquier usuario autenticado porque el permiso EnableLiveTvManagement se establece en verdadero por defecto para todos los usuarios nuevos. Un atacante puede encadenar estas vulnerabilidades añadiendo un sintonizador M3U que apunte a un servidor controlado por el atacante, sirviendo un M3U manipulado con un canal que apunte a la base de datos de Jellyfin, exfiltrando la base de datos para extraer tokens de sesión de administrador y escalando a privilegios de administrador. Este problema ha sido solucionado en la versión 10.11.7. Si los usuarios no pueden actualizar inmediatamente, pueden deshabilitar los privilegios de gestión de Live TV para todos los usuarios. -
