The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via text areas on forms in versions up to, and including, 3.1.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, which is the submissions page.

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to reCaptcha Bypass in versions up to, and including, 3.2.1. This is due to insufficient server side checking on the captcha value submitted during a form submission. This makes it possible for unauthenticated attackers to bypass Captcha restrictions and for attackers to utilize bots to submit forms.

The Metform WordPress plugin is vulnerable to sensitive information disclosure due to improper access control in the ~/core/forms/action.php file which can be exploited by an unauthenticated attacker to view all API keys and secrets of integrated third-party APIs like that of PayPal, Stripe, Mailchimp, Hubspot, HelpScout, reCAPTCHA and many more, in versions up to and including 2.1.3.
