CVE-2017-12677
IdentityServer3 2.4.x, 2.5.x, and 2.6.x before 2.6.1 has XSS in an Angular expression on the authorize response page, which might allow remote attackers to obtain sensitive information about the IdentityServer authorization response.
Does this matter?
Lower severity and a low EPSS score (1.04%). Track it; it rarely justifies an emergency change on its own.
