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 validate the URL scheme of a request-supplied value before reflecting it into a link on an admin page, allowing attackers to execute arbitrary JavaScript in the browser of a logged-in user who opens a crafted link.
