CNCF K3s Kubernetes kubelet configuration exposes credentials
Quick fix
GHSA-864f-7xjm-2jp2 — github.com/k3s-io/k3s: upgrade to the fixed version with the command below.
go get github.com/k3s-io/k3s@v1.32.4-rc1Details
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.
