GraphQL Security

GraphQL provides a powerful query language for APIs, but its flexibility introduces unique security challenges.

GraphQL-Specific Attacks

• Query depth attacks - Deeply nested queries that exhaust server resources
• Batch queries - Multiple queries in a single request
• Introspection leakage - Schema information exposure
• Field suggestion - Information leakage through error messages

Prevention

• Implement query depth limiting
• Set query complexity limits
• Disable introspection in production
• Implement rate limiting based on query complexity
• Use persisted queries
