CVE-2026-41068 Details
Description
Kyverno is a policy engine designed for cloud native platform engineering teams. The patch for CVE-2026-22039 fixed cross-namespace privilege escalation in Kyverno's `apiCall` context by validating the `URLPath` field. However, the ConfigMap context loader has the identical vulnerability — the `configMap.namespace` field accepts any namespace with zero validation, allowing a namespace admin to read ConfigMaps from any namespace using Kyverno's privileged service account. This is a complete RBAC bypass in multi-tenant Kubernetes clusters. An updated fix is available in version 1.17.2.
A vulnerability in Kyverno's ConfigMap context loader allows for cross-namespace privilege escalation by failing to validate the namespace field, enabling a namespace admin to read ConfigMaps from any namespace using Kyverno's privileged service account. This issue, present in versions through 1.17.0, bypasses role-based access control (RBAC) in multi-tenant Kubernetes clusters, where namespace isolation is crucial for security.
Users can update to Kyverno version 1.17.2, where this vulnerability has been patched by adding the necessary namespace validation in the ConfigMap context loader.
