原文摘录

摘自原文(2190 字符中的一小部分)
There is an issue with the https://www.yelp.com/signup/facebook endpoint which allows an attacker to validate whether a specific email address is registered on Yelp. There seems to be no rate limit nor a validation for already used CSRF tokens.
原文中的代码
first_name=<FIRSTNAME>&last_name=<LASTNAME>&fb_access_token=<FB_TOKEN>&email=<EMAIL>&post_csrf=<CSRF>&csrftok=<CSRFTOK>&password=<PASSWORD>&zip=<ZIP>
