Fetch vulnerability information from the national vulnerability database

[NoSpaces]

Hello to everyone!
I am in the process of trying to fetch vulnerability information from the national vulnerability database.
I found an app that can do this task via API - this is NVD-CVE-Fetcher-App.
The app link is here:
https://splunkbase.splunk.com/app/7121?ref=hub.metronlabs.com

The problem is that using NAT isn't allowed in our organization, so I was forced to use a proxy.
I tried to use a system proxy, but the application ignored the system setting and tried to access the API URL directly.
So, two questions:
1. Did anyone try to use the NVD-CVE-Fetcher-App in the proxy-acess scenario?
2. Did anyone resolve a similar task using other approaches? For example, another app or handmade script

Most probably (I don't know this app so I'm writing from general experience with several apps) proxy server must be explicitly defined for a given modular input. So if there are no settings within the app itself, you probably need to pester the autor of the app about it.

Thank you for your answer!
I have just been sent this information to the author.
But I am also interested in another experience related to my case 😃
