WP Editor < 1.2.6 - Cross-Site Request Forgery

The WP Editor plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to 1.2.6. This is due to missing or incorrect nonce validation on the save_settings() function, in addition to a few other functions. This makes it possible for unauthenticated attackers to modify the plugin's settings and upload files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
