Description

The Theme Changer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4. This is due to missing or incorrect nonce validation on the theme_changer_options() function. This makes it possible for unauthenticated attackers to update the 'theme_changer_password' option value granted they can trick a site administrator into performing an action such as clicking on a link.
