Description

CNCF K3s 1.32 before 1.32.4-rc1+k3s1 has a Kubernetes kubelet configuration change with the unintended consequence that in some situations ReadOnlyPort is set to 10255. For example the default behavior of a K3s online installation might allow unauthenticated access to this port exposing credentials.
