Dynamic Text Extension permits unauthenticated shortcode execution
Contact Form 7 - Dynamic Text Extension through 5.0.6 can pass an attacker-controlled value to do_shortcode without sufficient validation. An unauthenticated attacker can invoke shortcodes exposed by the site; the resulting impact depends on which plugins and shortcodes are installed. Version 5.0.4 only partially addressed the weakness.

Technical description
The The Contact Form 7 – Dynamic Text Extension plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.0.6. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The vulnerability was partially patched in version 5.0.4.
