api-auth-and-jwt-abuse

To test API authentication for JWT vulnerabilities, you analyze token trust boundaries, inspect claims for misuse, and check for common attack patterns like the alg:none bypass or weak signing secrets.

Bypassing API rate limiting often involves header spoofing and path variations to manipulate request identity signals, allowing you to detect weaknesses in the rate-limiting mechanisms protecting the endpoint.

Claim misuse compromises API security when bearer tokens are accepted without properly validating the issuer, audience, or token reuse, breaking the trust boundaries of the authentication implementation.

Yes, you can detect mass assignment and batch abuse vulnerabilities during API testing by identifying hidden fields and analyzing how the API processes request identity signals and mass assignment parameters.

Common attack patterns in JWT implementations include the alg:none attack, weak signing secrets, header spoofing, and insufficient validation of token trust boundaries during API authentication testing.
