NVD Description

Note: Versions mentioned in the description apply only to the upstream openstack-keystone package and not the openstack-keystone package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in OpenStack Keystone. This vulnerability allows remote authenticated users to bypass intended authorization restrictions. This occurs because OpenStack Keystone does not properly handle EC2 (Elastic Compute Cloud) tokens when a user's role has been removed from a tenant. An attacker can leverage a token associated with a removed user role to gain unauthorized access.
