The Yougler Blogger Profile Page plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, v1.01. This is due to missing or incorrect nonce validation on the 'yougler-plugin.php' page. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
