What it is

The Contact Form 7 – Dynamic Text Extension plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 5.0.5. This is due to insufficient output escaping on form shortcode keys displayed in the admin "Scan Forms for Post Meta and User Data Keys" page. This makes it possible for authenticated attackers, with Editor-level access and above, to inject arbitrary web scripts that execute when an Administrator runs the scan feature.
