CVE-2016-7138
Cross-site scripting (XSS) vulnerability in the URL checking infrastructure in Plone CMS 5.x through 5.0.6, 4.x through 4.3.11, and 3.3.x through 3.3.6 allows remote attackers to inject arbitrary web script or HTML via a crafted URL.
Does this matter?
Lower severity and a low EPSS score (1.59%). Track it; it rarely justifies an emergency change on its own.
