Vulnerability Details
Hi Snapchat Team, I've found a reflected XSS vulnerability on this page: https://www.snapchat.com/add/snapchat Example: https://www.snapchat.com/add/%22%3E%3Ch1%3EXSS%3C%2Fh1%3E Note: you should visit the page with a mobile user-agent since the server displays different information based on the User-Agent HTTP header sent by the browser. There are 6 places where the username isn't protected against XSS attacks: - 4 `meta` tags: twitter:title, twitter:image, og:title, og:image - 1 `object` tag: snapcode - 1 `h2` tag: username This could lead to JavaScript execution, UI redressing or open redirects.
