## Overview

The Advanced Contact form 7 DB plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.9. This is due to missing or incorrect nonce validation on the 'vsz_cf7_save_setting_callback' function. This makes it possible for unauthenticated attackers to delete form entry via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
