CVE-2026-9730: Remove NoFollow Commenter URL <= 1.0 - Cross-Site Request Forgery to Settings Update

The Remove NoFollow Commenter URL plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0. This is due to missing or incorrect nonce validation on the gmz_comment_settings_save function. This makes it possible for unauthenticated attackers to modify the plugin's comment-display setting via a forged request via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Analyst readout for executives and security teams

Plain-English summary

This CVE affects the WordPress Remove NoFollow Commenter URL plugin through version 1.0. A malicious site or link could trick a logged-in administrator into changing one plugin setting. The issue is limited to integrity impact in the cited sources, with no evidence of data theft, outage, or known active exploitation.

Executive priority

Treat as a moderate website hygiene issue. Prioritize affected public WordPress sites, especially where many administrators manage content. It is not presented as a breach-enabling flaw, but it can allow unauthorized configuration changes.

Technical view

The plugin’s gmz_comment_settings_save function lacks proper WordPress nonce validation, creating a CSRF condition. An unauthenticated attacker still needs administrator user interaction. The reported impact is modification of the plugin’s comment-display setting, rated CVSS 4.3 with low integrity impact only.

Likely exposure

Exposure is limited to WordPress sites running Remove NoFollow Commenter URL version 1.0 or earlier. Sites without this plugin are not affected by the cited issue.

Exploitation context

The source bundle does not show KEV listing or active exploitation. Exploitation requires social engineering a logged-in site administrator into taking an action that submits a forged settings update.

Researcher notes

The cited impact is narrow: CSRF to update a comment-display setting. Do not assume broader WordPress takeover, stored XSS, or data exposure without additional evidence. The affected-version metadata appears less clear than the narrative description, so verify against vendor records.

Mitigation direction

  • Inventory WordPress sites for Remove NoFollow Commenter URL version 1.0 or earlier.
  • Check vendor, WordPress plugin, and Wordfence guidance for a fixed release or official mitigation.
  • Disable or remove the plugin if no safe update is available and it is not essential.
  • Warn administrators against clicking untrusted links while authenticated to WordPress admin.

Validation and detection

  • Confirm whether the plugin is installed and record its version on each WordPress site.
  • Review the plugin settings for unexpected comment-display configuration changes.
  • Check whether gmz_comment_settings_save performs valid nonce verification in deployed code.
  • Review recent administrator sessions for suspicious setting changes or unusual referrers.
