Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to version 2.17.0, the /newsletter/image/images API endpoint is vulnerable to path traversal, allowing unauthenticated attackers to read arbitrary files from the application server's filesystem. This issue has been patched in version 2.17.0.
