| prequel-2025-0027 Low Impact: 5/10 Mitigation: 2/10 | Ingress Nginx Prefix Wildcard Error | The NGINX Ingress Controller rejects an Ingress manifest whose `pathType: Prefix` value contains a wildcard (`*`). Log excerpt: ``` ingress: default/api prefix path shouldn't contain wildcards ``` When the controller refuses the rule, it omits it from the generated `nginx.conf`; clients receive **404 / 502** responses even though the manifest was accepted by the Kubernetes API server. The problem appears most often after upgrading to ingress-nginx ≥ 1.8, where stricter validation was added. | Ingress Problems | ingress-nginx | NginxIngressKubernetes |
