OpenAM before 16.1.3 Open Redirect via Unverified id_token_hint in endSession

OpenAM before 16.1.3 contains an open redirect vulnerability that allows unauthenticated attackers to redirect users by supplying an unverified id_token_hint to the /oauth2/connect/endSession endpoint. Attackers can name any realm client in a forged hint to redirect victims to any registered post-logout URI, enabling phishing that borrows the OpenAM host's trust.
