PYSEC-2026-754
Openstack tripleo-heat-templates unauthenticated file access
Quick fix
PYSEC-2026-754 — tripleo-heat-templates: upgrade to the fixed version with the command below.
pip install --upgrade 'tripleo-heat-templates>=7.0.6'Details
A resource-permission flaw was found in the `tripleo-heat-templates` package where `ceph.client.openstack.keyring` is created as world-readable. A local attacker with access to the key could read or modify data on Ceph cluster pools for OpenStack as though the attacker were the OpenStack service, thus potentially reading or modifying data in an OpenStack Block Storage volume. This has been patched in versions [7.0.6](https://github.com/openstack/tripleo-heat-templates/commit/a18fd59077d97de83496c85c017b9d256a3eddd4) and [8.0.0](https://github.com/openstack/tripleo-heat-templates/commit/ce7b65f443d38a6627631f53cb22336338e97d30).
