Vulnerability in Tautulli (CVE-2026-41065)
Summary
Vulnerability in Tautulli (CVE-2026-41065). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Versions prior to 2.17.1 are vulnerable to remote code execution via the newsletter custom template directory feature. On a fresh install before the setup wizard is completed, all management endpoints are completely unauthenticated. An attacker can create a newsletter agent, point the custom template directory to an attacker-controlled SMB share serving a malicious Mako template, and trigger execution via the newsletter render endpoint, all with zero credentials and no local access to the target system. On a completed install with credentials configured, the same chain is exploitable by any admin. Version 2.17.1 fixes the issue.
