Doc Text:
A flaw was found in the VMware datastore driver of OpenStack glance_store. When an authenticated user supplies a crafted image location Uniform Resource Identifier (URI) pointing to an external host, the driver fails to validate the destination before forwarding requests. An attacker can exploit this issue to expose sensitive authentication headers and credentials to an unauthorized external server, resulting in information disclosure.
