CVE-2019-20435
A reflected XSS attack could be performed in the inline API documentation editor page of the API Publisher by sending an HTTP GET request with a harmful docName request parameter.
Does this matter?
Lower severity and a low EPSS score (1.08%). Track it; it rarely justifies an emergency change on its own.
