Pro Rank Tracker <= 1.0.0 is vulnerable to CSRF to Stored XSS Vulnerability

The Pro Rank Tracker plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.0. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
