CVE-2026-45381
Tautulli is a Python based monitoring and tracking tool for Plex Media Server.
Overview
CVE-2026-45381 is a known-severity vulnerability. It was published on September 21, 2026.
Technical description
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to 2.17.2, the /search endpoint inserts its user-controlled query parameter into a JavaScript string in data/interfaces/default/search.html using manual escaping that handles quotes and slashes but not backslashes. A backslash-quote sequence can terminate the string, so an unauthenticated attacker can send a crafted link that executes script in the Tautulli web context when an authenticated user follows it. This issue is fixed in version 2.17.2.
