CVE-2026-30963

Capsule is a multi-tenancy and policy-based framework for Kubernetes. To defend against namespace hijacking achieved through update/patch operations on namespaces, Capsule uses a webhook to validate update requests targeting namespaces. However, in Kubernetes, the namespace/finalize and...

CVE-2026-22872

Capsule is a multi-tenancy and policy-based framework for Kubernetes. The Capsule Controller runs with cluster-admin privileges. Although the TenantResource RawItems processing logic forcibly sets the namespace, this is ineffective for cluster-scoped resources. Prior to version 0.13.0, tenant...

CVE-2026-30963

Capsule (a Kubernetes multi-tenancy framework) relied on a webhook to validate namespace updates, but prior to v0.13.0 it did not intercept namespace/status or namespace/finalize subresource changes. This omission enables a tenant with permission to modify those subresources to hijack other names...
