What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The If-So Dynamic Content WordPress plugin before 1.10.2 does not escape a request-supplied value before reflecting it in an unauthenticated AJAX response that is served as HTML, allowing attackers to execute arbitrary JavaScript in the browser of a visitor who opens a crafted link.
