## Overview

In OpenStack Ironic through 35.0.1, when applying a PATCH to update fields in volume properties the user is authorized for, Ironic can return unredacted sensitive information (such as iSCSI credentials). The PATCH outcome is a security issue; the POST outcome is not a security issue.

## Affected packages

- `ironic >= 17.0.0, < 29.0.6`
- `ironic >= 30.0.0, < 32.0.2`
- `ironic >= 33.0.0, < 35.0.2`
- `ironic >= 36.0.0, < 37.0.1`

## Remediation

Upgrade to a patched release:

- `ironic 29.0.6`
- `ironic 32.0.2`
- `ironic 35.0.2`
- `ironic 37.0.1`
