## Affected

- chrisnowak Change WP URL: through 1.0

## Description

The Change WP URL plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0. This is due to missing or incorrect nonce validation on the 'change-wp-url' page. This makes it possible for unauthenticated attackers to change the WP Login URL via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
