{"apiVersion":"1.0","identifier":"CVE-2026-41065","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":"2026-06-04T15:16:53","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41065","cvssScore":8.9,"cvssVector":"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/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00434,"riskScore":0.92,"affectedProduct":"Tautulli","affectedVersions":"<2.17.1","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41065","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41065","en":"https://www.redsauce.net/en/cves/CVE-2026-41065","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41065","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41065","de":"https://www.redsauce.net/de/cves/CVE-2026-41065","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41065","el":"https://www.redsauce.net/el/cves/CVE-2026-41065"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41065"}}
