CVE-2026-87071 Details
Description
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.
A vulnerability exists in the Forminator Forms WordPress plugin in versions prior to 1.57.2.1, allowing unauthenticated users to inject arbitrary metadata into posts created through public forms. The plugin fails to restrict metadata keys, enabling the inclusion of keys reserved by WordPress.
Users are advised to update the Forminator Forms WordPress plugin to version 1.57.2.1 or later.
