CVE-2026-4138 Details
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.
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the DX Unanswered Comments plugin for WordPress, affecting all versions through 1.7. The issue arises from a lack of nonce validation on the plugin's settings form, allowing unauthenticated attackers to manipulate plugin settings, such as the authors list and comment count. This can be achieved by deceiving a site administrator into clicking a link that triggers the malicious request.
Users are advised to update to version 1.8 of the DX Unanswered Comments WordPress plugin, where this vulnerability has been patched.
