Kubernetes ingress-nginx controller
Wiz found that the ingress-nginx admission webhook could be made to load attacker config and run code, giving access to all cluster secrets the controller can read. CVSS 9.8. Fixed in controller v1.12.1 and v1.11.5; otherwise disable the validating webhook.
Why this severity: CVSS 9.8; unauthenticated RCE from the pod network
