The document discusses avoiding security issues when using GraphQL. It begins with an introduction to GraphQL concepts like queries, mutations and subscriptions. It then outlines potential security implications like information disclosure via introspection, denial of service attacks, IDOR and authorization bypass issues, and injections. The document recommends using the OWASP Secure Knowledge Framework (SKF) to help developers address these risks and build more secure GraphQL APIs. It provides an overview of SKF and demonstrates how to audit queries for security.
