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 Download Monitor WordPress plugin before 5.3.4 does not properly validate that a clicked link belongs to the site before fetching it client-side and rendering part of the response in the page, which allows unauthenticated attackers to execute arbitrary JavaScript in the browser of any user who is tricked into clicking a crafted link.
