NVD description

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.

    ⚠️ Command Execution Vulnerability Discovered in Prowler (CVE-2026-73263) A flaw in Prowler (< 5.36.0) allows attackers to achieve arbitrary command execution on shared worker nodes during Kubernetes provider connection tests. ⚙️ How it works: By supplying a malicious kubeconfig with legacy GCP auth-provider configurations (cmd-path / cmd-args), the system bypasses validation checks and executes attacker-controlled commands via subprocess.Popen. 🛡️ Fix: Upgrade to Prowler v5.36.0 or later immediately.

    Post summary

    CVE-2026-73263 permits arbitrary command execution on Prowler instances by exploiting malicious kubeconfig files; users should immediately upgrade to version 5.36.0 or newer.
