CVE-2026-8422

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. This makes it possible for unauthenticated attackers to modify or reset the plugin's per-role meta box visibility settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
