CVE-2025-1974 is a vulnerability within the Ingress NGINX Controller for Kubernetes, specifically affecting the admission controller component. This flaw falls under a group of vulnerabilities collectively known as "IngressNightmare." The vulnerability arises because the admission controllers are accessible over the network without authentication. By sending a malicious ingress object directly to the admission controller, an attacker can inject arbitrary NGINX configurations. This results in code execution on the Ingress NGINX Controller's pod, potentially granting unauthorized access to all secrets stored across all namespaces in the Kubernetes cluster, which could lead to a complete cluster takeover.

Description: A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
