Client Portal – Private user pages and login <= 1.1.8 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Client Portal – Private user pages and login plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.8. This is due to missing or incorrect nonce validation on the 'cp_create_private_pages_for_all_users' function. This makes it possible for unauthenticated attackers to create private pages via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
