Summary
The Forminator Forms WordPress plugin before 1.57.2.1 does not restrict which metadata keys a form submission may supply, and does not exclude the keys WordPress reserves for its own use, so unauthenticated visitors submitting a public form that collects post content can attach metadata of their choosing to the post their submission creates.
