What it is

The Easy Registration Forms WordPress plugin is vulnerable to Cross-Site Request Forgery due to missing nonce validation via the ajax_add_form function found in the ~/includes/class-form.php file which made it possible for attackers to inject arbitrary web scripts in versions up to, and including 2.1.1.
