Abusing GraphQL Introspection A Gateway for Recon and Exploitation

Abusing GraphQL Introspection A Gateway for Recon and Exploitation

GraphQL introspection can expose detailed schema information that attackers may exploit for various attacks. Proper configuration can significantly reduce security risks by disabling or limiting introspection features. #GraphQLIntrospection #SchemaDisclosure

Keypoints

  • GraphQL introspection reveals internal schema details useful for debugging and documentation.
  • Attackers can detect if introspection is enabled and dump schema information for exploitation.
  • Exploiting schema data can lead to privilege escalation, data exfiltration, or privilege misuse.
  • Advanced techniques include chaining mutations, testing access control, and brute-force field enumeration.
  • Disabling or restricting introspection is crucial to prevent sensitive information leaks and attack surface expansion.
