Over-fetching and Under-fetching: 

• Vulnerability: GraphQL's flexibility can lead to over-fetching (retrieving more data than needed) or under-fetching (not retrieving enough data). 
• Fix: Implement query whitelisting, schema validation, and authorization mechanisms to control data access. 

N+1 Query Problem: 

• Vulnerability: Repeated queries can lead to the N+1 query problem, causing excessive database calls. 
• Fix: Implement batching techniques or DataLoader to efficiently handle data-fetching and minimize database round-trips. 

Introspection Leakage: 

• Vulnerability: GraphQL's introspection feature can potentially expose sensitive schema details to attackers. 
• Fix: Disable introspection in production environments to prevent unauthorized schema access.
