Description
The MetForm plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.3.0 due to the metform-entry post type being registered with show_in_rest enabled while entries are stored as published posts. This makes it possible for unauthenticated attackers to list all form entries and read their titles and submission dates through /wp-json/wp/v2/metform-entry; titles contain submitted field values when the form's entry-title template references form fields.
