What is CVE-2026-35032?

Jellyfin, an open-source self-hosted media server, has a vulnerability in its LiveTV M3U tuner endpoint. This flaw allows local file reads through non-HTTP paths and enables Server-Side Request Forgery (SSRF) through HTTP URLs. Any authenticated user can exploit this insecurity due to the default permission settings, which grant 'EnableLiveTvManagement' privilege to all new users. An attacker can leverage this vulnerability chain by introducing a malicious M3U tuner URL that connects to a controlled server. This crafted M3U file can link to sensitive Jellyfin database information, resulting in unauthorized access and the potential exfiltration of admin session tokens. Users are advised to upgrade to version 10.11.7 for a fix or alternatively disable Live TV Management privileges as a mitigation step.
