Program ended up changing severity back to Critical, thankfully! :D Also big thanks to @ConspiracyProof , and @prashles for taking the time to look into the issue and helping! You guys rock, and are some of the best at @Hacker0x01 .
Being able to download every single customers PII data (name, phone, private addresses, po numbers, potentially financial data) through IDOR, through a simple number 8 digit value ID triaged as MEDIUM.... I can literally write a simple python script and own every user... What?

Replying to @ConspiracyProof
Part of the problem, in my opinion, is how quick the community is to cry "gate keeping!" when someone tries to pitch the angle of "hacking / security isn't for everyone / beginners". You need to understand software before you break it.

I’d really appreciate it if people would stop attributing Bug Bounty success with “Luck” Ain’t no fucking luck here! I hack 60+ hours a week(including learning) I was even putting those hours WITH a full time job for my first 4 months of hunting. I’ve EARNED my success.
