CVE-2019-16966
In the Contactmanager class (html\admin\modules\contactmanager\Contactmanager.class.php), an unsanitized group variable coming from the URL is reflected in HTML on 2 occasions, leading to XSS.
Does this matter?
Lower severity and a low EPSS score (1.14%). Track it; it rarely justifies an emergency change on its own.
