CRE-2025-0114 High Impact: 8/10 Mitigation: 6/10	Nginx Ingress Controller rewritten URI has a zero length	Detects rewrite error which leads to service unavailability.Wrong rewrite causes responses with HTTP code 500 or 400.This CRE detects empty rewrite.	Load Balancer Problems	nginx	Nginx Reverse Proxy Service Outage Ingress Controller NGINX Ingress Load Balancer Kubernetes
CRE-2025-0121 Critical Impact: 10/10 Mitigation: 7/10	NGINX Ingress Controller SSL Certificate Failure	Critical NGINX Ingress Controller SSL certificate validation failure detected. This pattern indicatescascading SSL failures where certificate verification errors lead to upstream connection failuresand service unavailability. The failure sequence shows SSL handshake failures, certificate verificationerrors, and resulting HTTP error responses that affect client connectivity.
