Doc Text:	An information exposure flaw in openstack-tripleo-heat-templates allows an external user to discover the internal IP or hostname. An attacker could exploit this by checking the www_authenticate_uri parameter (which is visible to all end users) in configuration files. This would give sensitive information which may aid in additional system exploitation.	Story Points:	---

Description Guilherme de Almeida Suckevicz 2021-12-27 17:43:49 UTC

According to parameter description, [keystone_authtoken] www_authenticate_uri should be public URL. However TripleO currently uses internal endpoint for this parameter.
