A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. (CVE-2026-54100)
A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. WMCO establishes SSH connections to Windows worker nodes without verifying the remote server host key. An adjacent-network attacker who can intercept or redirect WMCO's SSH session can capture WICD and kubelet bootstrap credentials transferred during node configuration, enabling compromise of Windows node identities in the cluster.
