CVE-2026-32254

CVE-2026-32254 (Kube-router) affects the kube-router proxy module in Kubernetes networking before version 2.8.0, where ExternalIPs and LoadBalancer IPs are not validated before being programmed into node network configurations. This can enable cluster-wide traffic hijacking and DNS DoS if malicio...
