Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

K3s (github.com/k3s-io/k3s) versions 1.32.0-rc1 up to but not including 1.32.4-rc1 are affected. A kubelet configuration change can set ReadOnlyPort to 10255 in some situations, which may allow unauthenticated network access to that port and expose credentials. Upgrade to 1.32.4-rc1 or later.
