Cross-Site Request Forgery in AJAX Report Comments WordPress Plugin

Publication date: 2026-06-09

Last updated on: 2026-06-09

Assigner: Wordfence

Description
The AJAX Report Comments plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.4. This is due to missing or incorrect nonce validation on the rc_options_page function. This makes it possible for unauthenticated attackers to modify plugin settings including link text and markup, success/failure/already-reported messages, comment threshold, cookie duration, reporter-comment toggle, and notification email address, subject, and message body via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Executive Summary

The AJAX Report Comments plugin for WordPress has a Cross-Site Request Forgery (CSRF) vulnerability in all versions up to and including 2.0.4. This occurs because the plugin's rc_options_page function lacks proper nonce validation, which is a security measure to verify legitimate requests.

As a result, an attacker who tricks a site administrator into clicking a malicious link can cause unauthorized changes to the plugin's settings without the administrator's consent.

Impact Analysis

This vulnerability allows unauthenticated attackers to modify various plugin settings by exploiting the administrator's interaction with a forged request.

  • Modification of link text and markup
  • Changing success, failure, or already-reported messages
  • Altering comment threshold and cookie duration
  • Toggling reporter-comment settings
  • Changing notification email address, subject, and message body

These unauthorized changes could disrupt the normal operation of the plugin, potentially leading to misinformation, misconfiguration, or abuse of the comment reporting functionality.

Mitigation Strategies

To mitigate this vulnerability, you should update the AJAX Report Comments plugin for WordPress to a version later than 2.0.4 where the nonce validation issue is fixed.

Additionally, avoid clicking on suspicious links that could trigger forged requests, especially if you are a site administrator.
