Does this matter?
Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.
Description
The Theme Editor plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1. This is due to missing nonce validation on the ms_update AJAX action. This makes it possible for unauthenticated attackers to modify child theme CSS styles via a forged request granted they can trick an administrator into performing an action such as clicking on a link.
