CVE-2022-39365Network attack vector

Remote code execution via unsafe Twig rendering

Published Oct 27, 2022 · Updated Apr 23, 2025

Server-side template injection in Pimcore before 10.5.9 allows remote attackers to execute arbitrary code via user-controlled Twig templates. Mail and Dynamic Text rendering compile attacker-controlled Twig without the restrictive sandbox added by the patch, allowing template expressions to invoke dangerous functionality. The CVSS record models unauthenticated network access without user interaction; successful exploitation can compromise confidentiality, integrity, and availability.
