Sandbox Escape in vm2@3.9.19 via custom inspect function

Summary

In vm2 for versions up to 3.9.19, Node.js custom inspect function allows attackers to escape the sandbox and run arbitrary code.

Proof of Concept

## MASTER NODE:

```sh
microk8s.add-node --token-ttl 3600 --format yaml --token $(openssl rand -hex 32)
```
## WORKER NODE

Using the previous output:

ngeorger

#!/usr/bin/bash
# This script is based on this one https://kevinsimper.medium.com/how-to-dump-all-kubernetes-secrets-to-yaml-files-b5afcf2d1f56
# But also it reads every namespace in your current default context and dumps it's secrets as a file named as the namespace and yml extension
# Tested on non-productive environments.
kubectl get namespaces | awk '{print $1}' | xargs -I{} sh -c 'kubectl get secrets -o yaml -n "$1" --no-headers >> "$1.yaml"' - {}
