Multiple Page Generator Plugin <= 3.3.9 - Cross-Site Request Forgery

The Multiple Page Generator Plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.3.9. This is due to missing or incorrect nonce validation on multiple functions. This makes it possible for unauthenticated attackers to flush and modify cache settings, download certain files, modify branding, and access data via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
