API SECURITY TESTING FOR AI-GENERATED APPS | VIBEEVAL

API Security is Critical

APIs are the backbone of modern applications and a primary attack vector. AI-generated APIs often have broken authorization, excessive data exposure, or missing security controls. Thorough API security testing is essential before launch.

API Security Testing Checklist

Follow these 10 steps to thoroughly test your API security. Critical items should be tested on every API endpoint before production deployment.

API authentication testing

Test authentication mechanisms including JWT validation, API key handling, and OAuth implementation.

Authorization testing

Verify that API endpoints enforce proper authorization and users cannot access unauthorized resources.

Input validation testing

Test all API parameters for injection vulnerabilities, type confusion, and input validation bypass.

Rate limiting verification

Test that rate limiting is properly implemented to prevent brute force attacks and API abuse.

Sensitive data exposure

Review API responses for excessive data exposure, PII leakage, and sensitive information in error messages.

Mass assignment testing

Test for mass assignment vulnerabilities where users can modify unauthorized fields through API parameters.

API versioning security

Verify that older API versions are properly deprecated and do not expose security vulnerabilities.

CORS configuration review

Test CORS policies to ensure only authorized origins can access your API endpoints.

GraphQL security testing

Test GraphQL endpoints for query depth limits, introspection exposure, and authorization bypass.

API documentation testing

Verify that API documentation does not expose internal endpoints or sensitive implementation details.

Common API Vulnerabilities

Broken Object Level Authorization

Users can access objects they should not have permission to view or modify by changing IDs in API requests.

Excessive Data Exposure

API returns more data than needed, exposing PII or sensitive information that clients should not receive.

Missing Rate Limiting

API endpoints lack rate limiting, allowing brute force attacks, credential stuffing, or resource exhaustion.

Mass Assignment

API allows modification of object properties that should be restricted, leading to privilege escalation.
