Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

Description

OpenAM before 16.1.3 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script by supplying crafted parameters rendered unencoded on the OAuth2 authorization error page. Attackers can lure victims to a crafted /oauth2/authorize link with repeated parameters to run JavaScript in the OpenAM origin, acting within existing sessions or redirecting to phishing pages.
