# API Reference: Detecting Privilege Escalation in Kubernetes Pods
## Kubernetes Python Client API
## Security Context Checks
| Method | Description |
|--------|-------------|
| `CoreV1Api().list_pod_for_all_namespaces()` | List all pods across namespaces |
| `CoreV1Api().list_namespaced_pod(namespace)` | List pods in a specific namespace |
| `RbacAuthorizationV1Api().list_cluster_role_binding()` | List all ClusterRoleBindings |
| `RbacAuthorizationV1Api().list_namespaced_role_binding(ns)` | List RoleBindings in namespace |
| Check | Risk | Description |
|-------|------|-------------|
| privileged: true | CRITICAL | Full host access |
| allowPrivilegeEscalation | HIGH | setuid escalation |
| runAsUser: 0 | HIGH | Running as root |
| hostPID: true | CRITICAL | Host PID namespace |
| hostNetwork: true | HIGH | Host network access |
## Pod SecurityContext Fields
## Dangerous Capabilities
| Field | Risk |
|-------|------|
| `privileged: true` | Full host access, container escape |
| `allowPrivilegeEscalation: true` | Enables setuid/setgid binaries |
| `runAsUser: 0` | Container runs as root |
| `hostPID: true` | Access to host process namespace |
| `hostNetwork: true` | Access to host network stack |
| `capabilities.add: [SYS_ADMIN]` | Near-root capabilities |
| Capability | Risk |
|------------|------|
| SYS_ADMIN | Container escape |
| SYS_PTRACE | Process debugging |
| SYS_MODULE | Kernel module loading |
| NET_ADMIN | Network manipulation |
## Key Libraries
## kubectl Audit Commands
- **kubernetes** (`pip install kubernetes`): Official Python client for Kubernetes API
- **config.load_kube_config()**: Load kubeconfig from file for external access
- **config.load_incluster_config()**: Load service account config when running inside a pod
```bash
kubectl get pods -A -o json | jq '.items[] | select(.spec.containers[].securityContext.privileged==true)'
kubectl auth can-i --list --as=system:serviceaccount:ns:sa
```
## Configuration
## Pod Security Standards
| Variable | Description |
|----------|-------------|
| `DANGEROUS_CAPABILITIES` | Linux capabilities that enable privilege escalation |
| `kubeconfig` | Path to Kubernetes configuration file |
```yaml
apiVersion: v1
kind: Namespace
metadata:
labels:
pod-security.kubernetes.io/enforce: restricted
```
