What are the security concerns around GraphQL?

GraphQL introduces several security concerns due to its flexible querying capabilities. Key issues include:

• Overly Broad Queries: Users can request large amounts of data or deeply nested information, potentially leading to performance issues or exposing sensitive data.

• Authorization Risks: Granular control is needed to ensure users access only permitted data, as GraphQL queries can request multiple data types in a single call.

• Injection Attacks: Like SQL injection, GraphQL can be vulnerable to injection attacks if inputs are not properly validated.

• Data Exposure: Schema design must be careful to avoid exposing sensitive fields or data unintentionally.

Addressing these concerns involves implementing strict access controls, limiting query complexity, and ensuring robust input validation.
