Exposure of Sensitive Information to an Unauthorized Actor in OpenStack tripleo-heat-templates

Quick fix

PYSEC-2026-753 — tripleo-heat-templates: upgrade to the fixed version with the command below.

pip install --upgrade 'tripleo-heat-templates>=11.6.1'

Details

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. A patch is available on the `master` branch and anticipated to be part of version 11.6.1.
