Summary
The Remove Yellow BGBOX 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 'rybb_api_settings' page. This makes it possible for unauthenticated attackers to reset the plugin's stored settings by overwriting its configuration via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
