CVE-2026-73263
CriticalCVSS 9.9Summary
Prowler before version 5.36.0 in the Kubernetes provider connection test accepts kubeconfig_content containing a legacy gcp auth-provider with config.cmd-path and config.cmd-args. Checking only exec blocks in kubeconfig_contains_exec_auth and loading via config.load_kube_config_from_dict causes kubernetes-python CommandTokenSource.token to run the attacker-supplied command through subprocess.Popen on the shared worker.
Risk Assessment
An attacker can execute arbitrary commands on the shared worker, potentially leading to security breaches in the cloud environment.
Recommendation
Update Prowler to version 5.36.0 or later, which includes the fix.
Original NVD description (English source)
Prowler is a cloud security platform. Prior to 5.36.0, the Kubernetes provider connection test accepted kubeconfig_content containing a legacy gcp auth-provider with config.cmd-path and config.cmd-args because kubeconfig_contains_exec_auth in api/src/backend/api/v1/serializers.py checked only exec blocks, and POST /api/v1/providers/{id}/connection loaded it through config.load_kube_config_from_dict in prowler/providers/kubernetes/kubernetes_provider.py, causing kubernetes-python CommandTokenSource.token to run the attacker-supplied command through subprocess.Popen on the shared worker. This issue is fixed in version 5.36.0.
