Grav CMS before 2.0.13 contains a server-side template injection vulnerability in email-action parameters that allows low-privileged page editors to execute arbitrary operating-system commands. Attackers can inject Twig payloads using the unsandboxed find filter in email subject, body, to, or from fields to achieve remote code execution when forms are submitted.
