CSRF Vulnerability in DX Unanswered Comments WordPress Plugin

Executive Summary

The DX Unanswered Comments plugin for WordPress has a vulnerability known as Cross-Site Request Forgery (CSRF) in all versions up to and including 1.7.

This vulnerability exists because the plugin's settings form in the dxuc-unanswered-comments-admin-page.php file lacks nonce validation.
