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