- GHSA-qvpr-qm6w-6rcc
details: OpenStack Keystone Essex (2012.1) and Folsom (2012.2) does not properly handle
  EC2 tokens when the user role has been removed from a tenant, which allows remote
  authenticated users to bypass intended authorization restrictions by leveraging
  a token for the removed user role.
