Kubernetes project issues warning on Ingress NGINX retirement

Kubernetes has announced that Ingress NGINX will reach end-of-life after March 2026 with no further releases or security fixes; the post warns organizations to immediately check for Ingress NGINX usage and begin migrating to Gateway API–conformant controllers. The report highlights a prior critical RCE (CVE-2025-1974, CVSS 9.8), recent high-severity CVEs disclosed in Feb 2026, and estimates that roughly 50% of cloud-native environments rely on Ingress NGINX—creating a significant unpatched risk if migration is delayed.
