What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
