CVE-2021-4403

Description

The Remove Schema plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5. This is due to missing or incorrect nonce validation on the validate() function. This makes it possible for unauthenticated attackers to modify the plugins settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
