Forminator – Contact Form, Payment Form & Custom Form Builder <= 1.29.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via forminator_form Shortcode

The Forminator – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id’ forminator_form shortcode attribute in versions up to, and including, 1.29.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
