Medium 4.3
In plain English
A medium-severity cross-site request forgery in DX Unanswered Comments from nofearinc. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 9% of all known vulnerabilities).
Official description
The DX Unanswered Comments plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.7. This is due to missing nonce validation on the plugin's settings form in the dxuc-unanswered-comments-admin-page.php file. This makes it possible for unauthenticated attackers to modify plugin settings (dxuc_authors_list and dxuc_comment_count) via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
