Kyverno, Go package github.com/kyverno/kyverno, versions up to and including 1.13.4, is vulnerable to server-side request forgery through its Service Call feature. An attacker who can create Kyverno policies in a Kubernetes cluster can make the policy send requests to an external server they control, which can expose data from cluster resources, including secrets. No fixed version is listed.
