The Post Grid, Slider & Carousel Ultimate WordPress plugin before 1.8.1 does not sanitise and escape one of its custom post type settings before outputting it in an HTML attribute on the admin edit screen, allowing users with the Contributor role and above to inject JavaScript that executes in the session of any administrator who opens the affected item.
