Advisory

Source description from Wordfence Intelligence, credited to István Márton.

The Free WooCommerce Theme 99fy Extension plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.7. This is due to missing or incorrect nonce validation on the 'plugin_activation' function. This makes it possible for unauthenticated attackers to activate arbitrary plugins already installed (but deactivated) on the site via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
