My Private Site <= 3.0.7 - Cross-Site Request Forgery

The plugin My Private Site for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.0.7. This is due to missing or incorrect nonce validation in the my_private_site_tab_advanced_process_buttons function. This makes it possible for unauthenticated attackers to inject malicious JavaScript, that will execute whenever a user accesses the /my_private_site_tab_advanced_process_buttons page, via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
