CVE-2026-45381 Details
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.
A reflected cross-site scripting vulnerability has been identified in Tautulli versions prior to 2.17.2. The issue arises in the '/search' endpoint, where the user-controlled 'query' parameter is improperly escaped before being inserted into a JavaScript string. This flaw allows an unauthenticated attacker to craft a link that, when followed by an authenticated user, executes scripts in the Tautulli web context.
Users can upgrade to Tautulli version 2.17.2 or later to address this vulnerability.
