DescriptionThe Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 1.52.1 via the 'upload-1[file][file_path]' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Successful exploitation requires a publicly accessible form with a File Upload field where Save and Continue is enabled in that form's Behavior settings and the Save and Continue email notification is configured to attach uploaded files in Email Notifications.
