SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill identifies critical security misconfigurations in Kubernetes manifests that could allow attackers to escalate privileges from a compromised pod to the underlying node or the entire cluster.

Core Features & Use Cases

  • Boundary Violation Detection: Flags dangerous hostPath mounts that expose sensitive node directories or container runtime sockets.
  • RBAC & NodeRestriction Analysis: Detects overprivileged node groups and improper impersonation roles that bypass standard security boundaries.
  • Scheduling Risk Assessment: Identifies broad tolerations that could allow untrusted workloads to execute on sensitive control-plane nodes.

Quick Start

Use the review-security-k8s-nodes skill to scan the deployment manifests in the current directory for potential node privilege escalation risks.

FAQPage Schema
How do I audit Kubernetes manifests for node privilege escalation risks?▼

Auditing Kubernetes manifests for node privilege escalation involves analyzing hostPath mounts, RBAC permissions, and scheduling tolerations to detect boundary violations and prevent node-to-cluster compromise.

How does hostPath mount usage expose Kubernetes node security vulnerabilities?▼

Dangerous hostPath mounts expose sensitive node directories or container runtime sockets, creating a boundary violation vector that allows attackers to escalate privileges from a compromised pod to the underlying node.

Can broad scheduling tolerations allow untrusted workloads on Kubernetes control-plane nodes?▼

Yes, broad scheduling tolerations can allow untrusted workloads to execute on sensitive control-plane nodes, posing a significant scheduling risk to overall cluster integrity and security boundaries.

What Kubernetes RBAC misconfigurations bypass NodeRestriction security boundaries?▼

Overprivileged node groups and improper impersonation roles bypass standard security boundaries, allowing attackers to escalate privileges and compromise the entire Kubernetes cluster via node access.

Do I need a live Kubernetes cluster to scan manifests for node security misconfigurations?▼

No, you do not need a live cluster. You can directly scan local deployment manifest files in your current directory to evaluate configurations against established security best practices.
