Vulnerability Overview

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.

Technical Analysis

REMEDIATION: Update to version 3.2.0, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
