Name of the Vulnerable Software and Affected Versions OpenShift Router (affected versions not specified)

Description A flaw in the OpenShift Router allows a user with EndpointSlice write access to proxy requests to a cloud metadata endpoint. This is achieved by creating a Service backed by a Fully Qualified Domain Name (FQDN) EndpointSlice that resolves to the metadata endpoint, bypassing security measures designed to validate IP addresses. This can lead to the disclosure of instance credentials and other sensitive metadata.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
