Pricing Table <= 2.0.1 - Cross-Site Request Forgery via ajax()

The Pricing Table plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.1. This is due to missing or incorrect nonce validation on the ajax() function. This makes it possible for unauthenticated attackers to perform a variety of actions related to managing pricing tables via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
