Description

Capsule is a multi-tenancy and policy-based framework for Kubernetes. From 0.13.0 until 0.13.8, after the incomplete CVE-2026-22872 fix, TenantResource RawItems and Generators in internal/controllers/resources/collect.go, including handleRawItem and handleGeneratorItem, did not apply the ResourceReference.LoadResources and IsNamespacedGVK cluster-scoped resource rejection guard used by NamespacedItems, allowing a Tenant Owner to create cluster-scoped resources such as ClusterRole or ValidatingWebhookConfiguration through the cluster-admin controller client. This issue is fixed in version 0.13.8.
