Just a reminder: with those bug bounty platforms like Bugcrowd, HackerOne or whatever, as a security researcher you are not their customer, you are the product.
If there is a conflict they will tend to side with their customer, meaning the company running the bug bounty program. Good luck proving that you have a right to disclose that vulnerability. They will pressure you into not disclosing as long as the company is opposed. So if you still want to decide anything it’s better not to grow too attached to that account because it will be used as leverage against you.
And they will try very hard to filter reports before these reach the company. If your report is more difficult to understand than the typical report for this program – good luck reaching the company, you’ll need it. It’s very likely that your report will be closed as “out of scope” with all appeals falling on deaf ears. The bug bounty platforms are paid for filtering, not for letting reports through just because they have doubts about them. You might need to think about other ways to reach the people actually in charge.
