WP Helper Premium < 4.5.2 - Cross-Site Request Forgery via whp_fields

Description

The WP Helper Premium plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.5.1. This is due to missing or incorrect nonce validation on the 'whp_fields' function. This makes it possible for unauthenticated attackers to update the plugin settingsvia a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
