CVE-2026-71325

A flaw was found in Traefik. This flaw allows a tenant, even when restricted by Role-Based Access Control RBAC to a single namespace, to bypass namespace isolation. By binding their own router to a TraefikService in another namespace, an attacker can expose or reroute that namespace's backend...

CVE-2026-54523

Kyverno is a policy engine designed for cloud native platform engineering teams. From 1.18.0 until 1.18.2, the NamespacedMutatingPolicy CEL compiler exposes the generator library to matchConditions, allowing a namespace-scoped policy to invoke generator.applynamespace, resources with an arbitrary...

GHSA-79GF-7FRW-68M9 Kyverno's NamespacedGeneratingPolicy generator.apply() namespace argument unvalidated -- background controller creates RoleBindings in any namespace including kube-system

Summary In Kyverno v1.18.1, a tenant who can create a NamespacedMutatingPolicy in their own namespace can instruct the admission controller to generate resources in any namespace by passing an arbitrary namespace string to the CEL generator.applynamespace, resources function. Details...
