CVE-2025-13520

The MTCaptcha WordPress Plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.7.2. This is due to missing or incorrect nonce validation on the settings update functionality. This makes it possible for unauthenticated attackers to update the plugin settings, including sensitive values like the private key, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
