  message: >-
    Found a Pyramid cookie without the httponly option correctly set.
    Pyramid cookies should be handled securely by setting httponly=True in response.set_cookie(...).
    If this parameter is not properly set, your cookies are not properly protected and
    are at risk of being stolen by an attacker.
