CVE-2017-9802
The Javascript method Sling.evalString() in Apache Sling Servlets Post before 2.3.22 uses the javascript 'eval' function to parse input strings, which allows for XSS attacks by passing specially crafted input strings.
Does this matter?
Lower severity and a low EPSS score (3.66%). Track it; it rarely justifies an emergency change on its own.
