Description
The Blocksy Companion plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.59 due to missing nonce validation on the blocksy_dashboard_handle_incorrect_license AJAX action, which deletes the active extensions option. This makes it possible for unauthenticated attackers to deactivate all of the plugin's extensions via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
