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.","state":0,"publishedAt":"2026-06-22T12:46:09.141+00:00","modifiedAt":"2026-10-14T02:41:42.519+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"openshift4-wincw/windows-machine-config-rhel9-operator","ranges":[],"versions":[],"rawVersionEvidence":"{\n
