OpenAM before 16.1.4 contains a stored cross-site scripting vulnerability that allows privileged attackers to inject script by placing markup in a user's display name. When the victim reaches the OAuth 2.0 / OpenID Connect consent page, the unencoded name executes script that can steal the OpenAM session cookie to impersonate the user.
