CVE-2020-1949
Scripts in Sling CMS before 0.16.0 do not property escape the Sling Selector from URLs when generating navigational elements for the administrative consoles and are vulnerable to reflected XSS attacks.
Does this matter?
Lower severity and a low EPSS score (1.97%). Track it; it rarely justifies an emergency change on its own.
