NGINX Gateway Fabric

An injection vulnerability in the NGINX Gateway Fabric configuration generator allows authenticated users to inject arbitrary NGINX directives into the configuration when using NGINX Plus as the data plane.

An injection vulnerability, CVE-2026-50107, exists in the NGINX configuration generator component of NGINX Gateway Fabric when configured with NGINX Plus or NGINX Open Source as the data plane, allowing authenticated attackers with CRD modification permissions to inject arbitrary NGINX configuration directives via unsanitized user-supplied string values in the access log format setting, leading to control plane compromise and potential defense evasion or system impact.
