## Overview

OpenStack Keystone Essex before 2012.1.2 and Folsom before folsom-3 does not properly handle authorization tokens for disabled tenants, which allows remote authenticated users to access the tenant's resources by requesting a token for the tenant.

## Affected packages

- `keystone < 8.0.0a0`

## Remediation

Upgrade to a patched release:

- `keystone 8.0.0a0`
