To mitigate the flaw, use an overcloud post-deploy script[1] to do the following on all overcloud nodes: key=/etc/ceph/ceph.client.openstack.keyring chown root:root $key chmod 600 $key setfacl -m u:glance:r $key setfacl -m u:cinder:r $key setfacl -m u:nova:r $key setfacl -m u: gnocchi:r $key If not using Red Hat OpenStack Platform director, then run the commands above manually on each overcloud node, Warning: Only running 'chmod 600 $key' alone (without an ACL) will prevent OpenStack from reading the key.
