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.
