Description
The Remove meta boxes per user role plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.01. This is due to missing or incorrect nonce validation on the 'remove-meta-boxes-per-user-role' page.

Analysis

AI-generated

Technical impact

The Remove meta boxes per user role plugin for WordPress contains a Cross‑Site Request Forgery flaw caused by missing or incorrect nonce validation on the "remove-meta-boxes-per-user-role" settings page. An unauthenticated attacker can craft a forged request and cause an administrator, if tricked into clicking a link or visiting a malicious URL, to unintentionally submit the request and modify or reset the plugin’s per‑role meta box visibility settings.

Affected Systems

WordPress sites that have the Remove meta boxes per user role plugin installed with version 1.01 or earlier are affected. The vulnerability is associated with the mr_mat vendor and applies to all releases up to and including 1.01.

Risk and Exploitability

The CVSS score of 4.3 places this issue in the moderate range. No EPSS score is available, and it is not listed in the CISA KEV catalog. Exploitation requires only that an attacker persuade a site administrator to submit a forged request; no additional credentials or system access is necessary. Successful exploitation results in unauthorized changes to the plugin’s configuration, affecting how meta boxes appear in the WordPress admin interface.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the Remove meta boxes per user role plugin to the latest version, which includes proper nonce validation.
  • If updating is not immediately possible, disable the plugin entirely to eliminate the CSRF vector.
  • Consider restricting unauthenticated access to the plugin’s settings page through a WordPress security plugin or an .htaccess rule to add an extra layer of protection.
