Summary

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.

Risk Assessment

The risk includes remote code execution on the server, which could lead to full system compromise, data theft, or service disruption.

Recommendation

It is recommended to upgrade the Grav Email plugin to version 4.2.2 or later and restrict API permissions to trusted users.
