What it is

The AI Builder WordPress plugin before 2.7.8 does not sanitise custom JavaScript saved against a post before echoing it inside a script tag on the front end, allowing users with contributor level access and above to store arbitrary JavaScript that will execute in the browser of anyone who views the post, including the editor or administrator who reviews it.
