Technical details

A denial-of-service vulnerability exists in NGINX Gateway Fabric when configured with GRPCRoutes. The issue is caused by improper validation of array indexes (CWE-129) within the control plane when processing GRPCRoute configurations that contain backendRef filters. An authenticated remote attacker with the necessary Kubernetes RBAC permissions to create or modify GRPCRoute resources can submit a crafted configuration that triggers a process termination. This affects versions 1.3.0 through 2.6.3; users should update to version 2.6.4 or later to resolve the issue.
