Three unpatched high-severity security flaws have been disclosed in the NGINX Ingress controller for Kubernetes that could be weaponized by a threat actor to steal secret credentials from the cluster. The vulnerabilities are as follows -  CVE-2022-4886 (CVSS score: 8.8) - Ingress-nginx path sanitization can be bypassed to obtain the credentials of the ingress-nginx controller CVE-2023-5043 (

Kube-proxy on Windows can unintentionally forward traffic to local processes listening on the same port (“spec.ports[*].port”) as a LoadBalancer Service when the LoadBalancer controller does not set the “status.loadBalancer.ingress[].ip” field. Clusters where the LoadBalancer controller sets the “status.loadBalancer.ingress[].ip” field are unaffected.

Preventative security should be driven by data and risk assessment, not compliance.
