Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/openshell, Red Hat/openshift/ose-rhel-coreos-8, Red Hat/openshift/ose-rhel-coreos-9.
  2. 2Review the reported fix. Source-reported workaround: Do not use sftp to copy from a server you do not trust. There is no configuration switch that closes this path.
