CVE-2026-56743

Cilium (versions 1.19.0–1.19.4) is affected where standard Kubernetes NetworkPolicy ipBlock rules without pod/namespace selectors, when configured with a non-default clusterName, can generate a wildcard namespace allow rule. The parser incorrectly creates a pod selector for selectorless peers, en...
