CVE-2026-72827 is a server-side template injection vulnerability in Grav CMS affecting versions before 2.0.13. The flaw resides in email-action parameters used by form handling, where attacker-controlled fields such as email subject, body, recipient, or sender values can be rendered as Twig templates without sandbox restrictions. Low-privileged page editors can inject Twig expressions that abuse the unsandboxed find filter, resulting in arbitrary operating-system command execution when a form submission triggers processing of the email action.
