👩🎓👨🎓 Learn about GraphQL API vulnerabilities! The user management functions for this lab are powered by a GraphQL endpoint. The endpoint accepts requests with a content-type of 'x-www-form-urlencoded' and is therefore vulnerable to cross-site request forgery (CSRF) attacks. To solve the lab, we must craft some HTML that uses a CSRF attack to change the viewer's email address, then upload it to your exploit server.
