## Overview

An issue was discovered in OpenStack Cinder before 19.1.2, 20.x before 20.0.2, and 21.0.0; Glance before 23.0.1, 24.x before 24.1.1, and 25.0.0; and Nova before 24.1.2, 25.x before 25.0.2, and 26.0.0. By supplying a specially created VMDK flat image that references a specific backing file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data.

## Affected packages

- `cinder < 19.1.2`
- `cinder >= 20.0.0, < 20.0.2`
- `glance < 23.0.1`
- `glance >= 24.0.0, < 24.1.1`
- `nova < 24.1.2`
- `nova >= 25.0.0, < 25.0.2`

## Remediation

Upgrade to a patched release:

- `cinder 19.1.2`
- `cinder 20.0.2`
- `glance 23.0.1`
- `glance 24.1.1`
- `nova 24.1.2`
- `nova 25.0.2`
