Easy PayPal Events < 1.3 - Cross-Site Request Forgery

Description

The Easy PayPal Events plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.2. This is due to missing or incorrect nonce validation on the wpplugin_paypal_button_load_scripts() function. This makes it possible for unauthenticated attackers to send test emails via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
