## Description

The TripleO Heat templates (tripleo-heat-templates) do not properly order
the Identity Service (keystone) before the OpenStack Object Storage (Swift)
staticweb middleware in the swiftproxy pipeline when the staticweb
middleware is enabled, which might allow remote attackers to obtain
sensitive information from private containers via unspecified vectors.
