The book starts with GraphQL foundations, then guides readers in building a GraphQL security lab using common tools and vulnerable targets. It systematically covers attack surface discovery, denial-of-service techniques, information disclosure through schema and errors, authentication and authorization bypasses, multiple injection classes, and request forgery/hijacking scenarios, ending with real-world disclosed vulnerabilities and exploits.","CONTENTS IN DETAIL  \nTITLE PAGE  \nCOPYRIGHT  \nABOUT THE AUTHORS  \nFOREWORD
