Integration for Contact Form 7 HubSpot <=1.3.1 - Cross-Site Request Forgery

Description

The Integration for Contact Form 7 HubSpot plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.1. This is due to missing or incorrect nonce validation on the settings_page function. This makes it possible for unauthenticated attackers to change the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
