Good morning,
could you please align to the official NVD NIST cpe "f5:nginx"? There is no cpe "f5:nginx_open_source", F5 NGINX Open Source and F5 Nginx Server are the same thing. These are two different names for the same product, the free and open source web server based on the NGINX project.
We would appreciate it very much.
Best Regards,
