WP Easy Pay – Payment and Donation form Builder for Square < 4.5.1 - Cross-Site Request Forgery

Description

The WP Easy Pay – Payment and Donation form Builder for Square plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.5.0. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
