| Doc Text: |
A flaw was found in Kyverno, a policy engine for Kubernetes. This vulnerability allows attackers with low privileges to exfiltrate the admission controller's ServiceAccount token. By directing `apiCall` requests to external or attacker-controlled endpoints, the token is automatically attached without explicit authorization headers. This unauthorized access can lead to attackers gaining full control over Kyverno policies and cluster resources.
