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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • mndpsingh287 Theme Editor — Up to and including 3.1
