Summary

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

Risk Assessment

JavaScript injection can lead to administrator session hijacking, data theft, or unauthorized actions in the admin panel. This is a serious risk to site security.
