Detailsinfo A vulnerability classified as critical was found in Jellyfin up to 10.11.6. Affected by this vulnerability is an unknown part of the file /LiveTv/TunerHosts. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is: 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. The advisory is shared at github.com. This vulnerability is known as CVE-2026-35032 since 03/31/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. Upgrading to version 10.11.7 eliminates this vulnerability. The upgrade is hosted for download at github.com.
