Description
The Page Blocks plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.0. This is due to missing or incorrect nonce validation on the admin_process_widget_page_change function. This makes it possible for unauthenticated attackers to modify widget page block configurations via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
