Foxtool All-in-One: Contact chat button, Custom login, Media optimize images <= 2.5.2 - Cross-Site Request Forgery to Google OAuth Connection

The Foxtool All-in-One: Contact chat button, Custom login, Media optimize images plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.5.2. This is due to missing or incorrect nonce validation on the foxtool_login_google() function. This makes it possible for unauthenticated attackers to establish an OAuth Connection via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
