OWASP API Security Top 10 (2023)

API1

Broken Object Level Authorization

APIs expose endpoints handling object identifiers, creating a wide attack surface.

API2

Broken Authentication

Authentication mechanisms are often implemented incorrectly.

API3

Broken Object Property Level Authorization

Lack of or improper authorization validation at object property level.

API4

Unrestricted Resource Consumption

APIs do not restrict the size or number of resources that can be requested.

API5

Broken Function Level Authorization

Complex access control policies with different hierarchies and roles.

API6

Unrestricted Access to Sensitive Business Flows

APIs vulnerable to automation of sensitive business flows.

API7

Server Side Request Forgery

SSRF flaws occur when an API fetches remote resources without validating the URI.

API8

Security Misconfiguration

APIs and supporting systems often contain misconfigurations.

API9

Improper Inventory Management

APIs tend to expose more endpoints, making proper documentation crucial.

API10

Unsafe Consumption of APIs

Developers trust data from third-party APIs more than user input.

Frequently Asked Questions

What is the OWASP API Security Top 10?
OWASP API Security Top 10 is a list of the most critical security risks for APIs: 1) Broken Object Level Authorization (BOLA), 2) Broken Authentication, 3) Broken Object Property Level Authorization, 4) Unrestricted Resource Consumption, 5) Broken Function Level Authorization, 6) Unrestricted Access to Sensitive Business Flows, 7) Server Side Request Forgery, 8) Security Misconfiguration, 9) Improper Inventory Management, 10) Unsafe Consumption of APIs.
How do I test my API for security vulnerabilities?
Enter your API endpoint URL, select the HTTP method (GET, POST, PUT, DELETE), add any required headers or authentication tokens, and click Scan. Our scanner will check for OWASP Top 10 vulnerabilities, authentication issues, rate limiting, injection flaws, and security misconfigurations.
What is Broken Object Level Authorization (BOLA)?
BOLA (also known as IDOR - Insecure Direct Object Reference) occurs when an API doesn't properly verify that a user has permission to access a specific resource. Attackers can manipulate object IDs in requests to access unauthorized data. This is the #1 API vulnerability according to OWASP.
Is this API security scanner free to use?
Yes! Our basic API security scanner is completely free. It checks for common vulnerabilities including authentication issues, security headers, rate limiting, and basic injection flaws. For comprehensive enterprise testing with advanced features, consider our premium options.
Can I test GraphQL APIs with this scanner?
Yes! Our scanner supports both REST and GraphQL APIs. For GraphQL, we check introspection exposure, query depth limits, batching attack vectors, and field-level authorization. Enter your GraphQL endpoint and we'll automatically detect the API type.
What security headers should my API have?
Essential API security headers include: Strict-Transport-Security (HSTS), X-Content-Type-Options: nosniff, X-Frame-Options: DENY, Content-Security-Policy, X-XSS-Protection, Cache-Control for sensitive data, and proper CORS configuration with Access-Control-Allow-Origin.
