This release updates Kubernetes to v1.31.7, and upgrades rke2-ingress-nginx to controller v1.12.1-hardened1 (chart version 4.12.1). This addresses CVE-2025-1974 as well as all other recently announced vulnerabilities in ingress-nginx.
Important Note
If your server (control-plane) nodes were not started with the --token CLI flag or config file key, a randomized token was generated during initial cluster startup. This key is used both for joining new nodes to the cluster, and for encrypting cluster bootstrap data within the datastore. Ensure that you retain a copy of this token, as is required when restoring from backup.
You may retrieve the token value from any server already joined to the cluster:
