Authenticated code execution via unrestricted dynamic callable
Published Jul 21, 2026 · Updated Jul 21, 2026
Code injection in Grav before 2.0.7 allows remote authenticated users with page-write access to execute commands as the web-server user. Blueprint::dynamicData() passes an attacker-controlled Class::method string and arguments to call_user_func_array() without an allowlist. A holder of admin.pages or api.pages.write can plant the directive in page frontmatter, and any later page visit triggers it with the web server's permissions.
