## Overview

## Summary:
A potential risk in clusternet which can be leveraged to make a cluster-level privilege escalation.
## Detailed analysis:
The clusternet has a deployment called cluster-hub inside the clusternet-system Kubernetes namespace, which runs on worker nodes
randomly. The deployment has a service account called clusternet-hub, which has a cluster role called clusternet:hub via cluster role binding. The clusternet:hub cluster role has "*" verbs of "*.*" resources. Thus, if a malicious user can access the worker node which runs the clusternet, he/she can leverage the service account to do malicious actions to critical system resources. For example, he/she can leverage the service account to get ALL secrets in the entire cluster, resulting in cluster-level privilege escalation.

## Affected packages

- `github.com/clusternet/clusternet < 0.15.2`

## Remediation

Upgrade to a patched release:

- `github.com/clusternet/clusternet 0.15.2`
