kube-router: BGP Peer Passwords Exposed in Logs at Verbose Logging Level

Summary When kube-router is configured with per-node BGP peer passwords using the kube-router.io/peer.passwords node annotation, and verbose logging is enabled --v=2 or higher, the raw Kubernetes node annotation map is logged verbatim — including the base64-encoded BGP MD5 passwords. Anyone with...
