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.\n\n## Affected packages\n\n- `github.com/clusternet/clusternet < 0.15.2`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/clusternet/clusternet 0.15.2`","depth":"sunlit","depthScore":37,"depthScoreParts":{"impact":36.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
