## Overview

An information leak was discovered in OpenStack heat. This issue could allow a remote, authenticated attacker to use the 'stack show' command to reveal parameters which are supposed to remain hidden. This has a low impact to the confidentiality, integrity, and availability of the system.

## Affected packages

- `openstack-heat < 20.0.0`

## Remediation

Upgrade to a patched release:

- `openstack-heat 20.0.0`
