Overview
keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.
Affected versions of this package are vulnerable to Incorrect Authorization in the POST /v3/credentials endpoint. An attacker can gain unauthorized access to resources across different projects by supplying a mismatched project_id when creating EC2-type credentials, which allows lateral movement within the role footprint of the credential owner.
