Description

The Formidable Forms WordPress plugin before 6.3.1 does not adequately authorize the user or validate the plugin URL in its functionality for installing add-ons. This allows a user with a role as low as Subscriber to install and activate arbitrary plugins of arbitrary versions from the WordPress.org plugin repository onto the site, leading to Remote Code Execution.
