testing-api-authentication-weaknesses

You can test API authentication weaknesses by running an automated agent script against your API base URL to detect JWT alg:none vulnerabilities, weak secrets, missing expiration claims, and token leakage in URLs or logs.

Yes, you can automate token revocation and session lifecycle testing for REST APIs by analyzing token refresh flows, detecting token reuse scenarios, and evaluating account enumeration vulnerabilities across your development and staging environments.

The best way to detect JWT token leakage during API security testing is to automate the analysis of tokens, endpoints, and session data to identify sensitive tokens exposed in URLs or logs across REST and GraphQL services.

This API authentication testing tool works with both GraphQL and REST APIs, analyzing tokens, endpoints, and session lifecycle across services to uncover broken authentication vectors in development and security assessment scenarios.

Yes, you need Python 3.x and the included agent script to run automated JWT security testing, with the requests library serving as an optional dependency for executing network calls against your API base URL.

API authentication test reports show account enumeration vulnerabilities when the automated analysis identifies endpoints that leak valid user information during token evaluation, session management, and authentication flow testing across services.
