CVE-2026-75574 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. The Grav Email plugin (getgrav/grav-plugin-email) before 4.2.2 renders page-editor-controlled Email action parameters as unsandboxed Twig templates. An authenticated remote user with only api.access and api.pages.write permissions can place a Twig expression in header.form.process.email.body, publish the page, and submit the form to execute an arbitrary operating-system command as the account running PHP.. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
