Shopify: Removing parts of URL from jQuery request exposes links for download of Paid Digital Assets of the most recent Order placed by anyone on the store!

Please Note: I found this bug on a website made using Shopify I tried doing the same with my Shopify store but I was not able to buy anything as it was required to add credit card details which I don't have : THE LINKS GIVEN AS THE EXAMPLE ARE NOT VALID LINKS BUT THE BUG WORKS ON EVERY SHOPIFY...
