The most serious of today’s vulnerabilities, [CVE-2025-1974](https://github.com/kubernetes/kubernetes/issues/131009), rated [9.8 CVSS](https://www.first.org/cvss/calculator/3-1#CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), allows anything on the Pod network to exploit configuration injection vulnerabilities via the Validating Admission Controller feature of ingress-nginx. This makes such vulnerabilities far more dangerous: ordinarily one would need to be able to create an Ingress object in the cluster, which is a fairly privileged action. When combined with today’s other vulnerabilities, **CVE-2025-1974 means that anything on the Pod network has a good chance of taking over your Kubernetes cluster, with no credentials or administrative access required**. In many common scenarios, the Pod network is accessible to all workloads in your cloud VPC, or even anyone connected to your corporate network\! This is a very serious situation.
