Technical details
Kyverno's Service Call functionality is intended to reach internal Kubernetes services but fails to restrict requests to in-cluster addresses, allowing resolution of external URLs. The vulnerability is a server-side request forgery (CWE-918) in the apiCall/service configuration of ClusterPolicy and Policy resources. An attacker with policy creation permissions (typically cluster administrators but potentially lower-privileged users in multi-tenant environments) can craft a policy that sends HTTP POST requests containing policy context data—including Kubernetes resource contents and secrets—to an attacker-controlled external server. No special network configuration is required; the attack requires only the ability to create or modify cluster policies. Patches are available in version 1.13.4 and later.
