GraphQL Endpoint Detected

Remediation

To secure GraphQL endpoints and reduce information disclosure risks, implement the following security measures:

1. Implement proper authentication and authorization: Ensure all GraphQL endpoints have appropriate authentication mechanisms and field-level authorization controls.

   Example (GraphQL with JWT authentication):

   const resolvers = {
     Query: {
       sensitiveData: (parent, args, context) => {
         if (!context.user) {
           throw new AuthenticationError('Authentication required');
         }
         return getSensitiveData(context.user);
       }
     }
   };
   

2. Configure security middleware: Use GraphQL security middleware to implement query depth limiting, complexity analysis, and rate limiting.

   Example (GraphQL Depth Limit):

   const depthLimit = require('graphql-depth-limit');
      
   const server = new ApolloServer({
     typeDefs,
     resolvers,
     validationRules: [depthLimit(5)]
   });
   

3. Disable introspection in production: Ensure introspection queries are disabled in production environments to prevent schema disclosure.

4. Implement query whitelisting: Use persisted queries or query whitelisting to control which operations are allowed in production.

About

This detection identifies GraphQL endpoints by analyzing HTTP requests and responses for GraphQL-specific patterns, server signatures, and endpoint paths. GraphQL endpoints can expose significant functionality through a single URL, making proper security configuration critical. The fingerprinting process examines request/response patterns, content types, server headers, and GraphQL-specific syntax to identify the presence and characteristics of GraphQL implementations.

Risks

The risks associated with improperly secured GraphQL endpoints include:

• Information disclosure: GraphQL endpoints may expose more data than intended through overfetching or lack of field-level authorization.
• Denial of service: Complex queries, deep nesting, or batch operations can cause resource exhaustion if not properly limited.
• Authentication bypass: Poorly configured GraphQL endpoints may allow unauthorized access to sensitive operations or data.
• Injection attacks: GraphQL queries that incorporate user input without proper validation may be vulnerable to injection attacks.
