api-auth-and-jwt-abuse

To test JWT algorithm confusion and unsigned token acceptance, you must triage token header fields like `alg`, `kid`, `jku`, and `x5u` to identify where the API improperly assigns trust to forged identity signals. This targets common failure modes in token validation.

The best way to bypass API rate limiting involves probing identity spoofing via common proxy identity headers and planning batch or mass-assignment style request patterns to overwhelm or circumvent throttling controls across REST or GraphQL endpoints.

Claim abuse in API authentication works by manipulating issuer, audience, and claim integrity within bearer tokens or API keys to exploit authorization weaknesses, leading to unauthorized access or privilege escalation when token trust boundaries are improperly enforced.

Yes, you can test both REST and GraphQL endpoints for token trust boundary flaws. The testing process applies to both architectures to identify weaknesses in JWT-based authorization, forged identity signals, and rate-limit bypass opportunities.

Your API accepts forged JWT headers because of key lookup trust issues and improper validation of header fields like `kid`, `jku`, and `x5u`. Testing these fields reveals where token trust boundaries fail and allows unauthorized access.
