Easy PayPal Events <= 1.2.1 - Cross-Site Request Forgery to Arbitrary Post Deletion

The Easy PayPal Events plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.1. This is due to missing or incorrect nonce validation on the wpeevent_plugin_buttons() function. This makes it possible for unauthenticated attackers to delete arbitrary posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
