What the vulnerability does
01Description
The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.8.1. This is due to missing or incorrect nonce validation on the contents function. This makes it possible for unauthenticated attackers to update the options "mf_hubsopt_token", "mf_hubsopt_refresh_token", "mf_hubsopt_token_type", and "mf_hubsopt_expires_in" via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This would allow an attacker to connect their own Hubspot account to a victim site's metform to obtain leads and contacts.
Explanation of Vulnerability in Simple Terms
02Summary
MetForm versions up to 3.8.1 are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the form builder without the admin's knowledge or consent. This could allow unauthorized modification of forms, surveys, or quizzes. No special privileges or technical access are required beyond tricking a user into visiting a malicious link.
