{"id":"CVE-2026-41065","state":"PUBLISHED","title":"Tautulli Vulnerable to Unauthenticated/Authenticated Remote Code Execution via Newsletter Custom Template Directory","description":"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.","publishedAt":"2026-06-04T14:17:13.238Z","updatedAt":"2026-06-04T14:28:51.267Z","severity":{"score":8.9,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","source":"GitHub_M"},"assigner":"GitHub_M","products":["Tautulli Tautulli"],"affected":[{"vendor":"Tautulli","product":"Tautulli","versions":[{"version":"< 2.17.1","status":"affected"}]}],"references":["https://github.com/Tautulli/Tautulli/security/advisories/GHSA-68qx-mcf5-3jcp","https://github.com/Tautulli/Tautulli/releases/tag/v2.17.1"],"weaknesses":["CWE-1336"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/41xxx/CVE-2026-41065.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-41065","state":"PUBLISHED","datePublished":"2026-06-04T14:17:13.238Z","dateUpdated":"2026-06-04T14:28:51.267Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-16T16:43:03.173Z"},"containers":{"cna":{"title":"Tautulli Vulnerable to Unauthenticated/Authenticated Remote Code Execution via Newsletter Custom Template Directory","descriptions":[{"lang":"en","value":"Tautulli is a Python based monitoring and tracking tool for Plex Media Server.
