Hello Friends, I'm gonna share my interesting finding here. Recently,  About two months ago,  I received a private invitation on Bugcrowd and the next day I started to look for bugs on that website because there was only one target (testing site) in scope and they provided me some credentials. I can't disclose the site name, so let's assume https://redacted.com First of all, I logged-in to that site (redacted.com) with the provided credentials and inspected the site around 15 minutes and tried to understand it. After that, I started to look for bugs and found multiple bugs mostly stored XSS. At that day, I had found a total 11 vulnerabilities. I reported them and received a bounty on each report.

But on someone request, I share some of my bug bounty findings here. I like to find some interesting and logical bugs. Recently, I found an interesting bug in many sites but I can't disclose the name of every website, one website 'Upwork' already patched this bug and resolved the report that's why I disclose the name.
