Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Capsule is a multi-tenancy and policy-based framework for Kubernetes. Prior to 0.13.8,
 CapsuleConfiguration.Spec.NodeMetadata.ForbiddenLabels.Regex and
 CapsuleConfiguration.Spec.NodeMetadata.ForbiddenAnnotations.Regex were not validated by the configuration
 admission webhook, allowing a Cluster Admin to store a malformed regex that later reached
 regexp.MustCompile in pkg/api/forbidden_list.go through internal/webhook/node/user_metadata.go and crashed
 the node admission webhook on Node create, update, or patch requests. This issue is fixed in version
 0.13.8. (CVE-2026-65834)
