Summary

Grav 2.0.4 (fixed in 2.0.7) contains a remote code execution vulnerability in Blueprint::dynamicData() (system/src/Grav/Common/Data/Blueprint.php), which passes a Class::method callable string and its arguments directly to call_user_func_array() without any allowlist. Because the form plugin routes page frontmatter through this path, an authenticated account with the admin.pages (or api.pages.write) permission can plant a malicious callable directive in a page. The command then executes as the web-server user whenever anyone — including an unauthenticated visitor — accesses the page.
