How to fix?

There is no fixed version for RHEL:8 openshift4-wincw/windows-machine-config-rhel8-operator.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4-wincw/windows-machine-config-rhel8-operator package and not the openshift4-wincw/windows-machine-config-rhel8-operator package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. The WICD CSR auto-approver validates that a Certificate Signing Request contains the organization system:wicd-nodes but does not reject additional organization values such as system:masters. A compromised Windows worker node that holds WICD credentials can submit a CSR that is auto-approved and signed by the cluster, yielding a client certificate that grants cluster-administrator privileges and enabling full cluster takeover.
