Description

The Calculated Fields Form plugin for WordPress is vulnerable to HTML Injection in all versions up to, and including, 5.2.45. This is due to the plugin not properly neutralizing HTML elements from submitted forms. This makes it possible for unauthenticated attackers to inject arbitrary HTML that will render when the administrator views form submissions in their email.
