UnverifiedBaseResponse extracts several basic attributes of a SAML Response which may be useful in deciding how to validate the Response. An UnverifiedBaseResponse is parsed by this library prior to any validation of the Response, so the values it contains may have been supplied by an attacker and should not be trusted as authoritative from the IdP.
