To test JWT vulnerabilities such as alg:none bypass and algorithm confusion, provide a token and base URL to automate detection of signing misconfigurations. The tool identifies header injection risks and missing claims, exposing findings with recommended mitigations for web app and API security.

A JWT algorithm confusion attack exploits weak signing configurations by manipulating the token header to bypass verification. This automated testing identifies such misconfigurations, missing exp, iss, or aud claims, and header-based injection risks to prevent token abuse in OAuth2 or SSO deployments.

Yes, you can scan JWT authentication in both development and production environments. The analysis comprehensively checks token structure and claims to identify missing or weak controls regarding expiration, issuer, and audience, providing remediation guidance for API security.

To detect kid, jku, or x5u header injections in JWT tokens, run an automated analysis against the provided token string. The testing workflow exposes header-based injection risks and misconfigurations, delivering a report with practical remediation steps to secure authentication.

Yes, the requests library is required as a dependency to perform JWT pentesting and token analysis. It facilitates the automated security testing of web apps and APIs by sending requests to the specified base URL to validate token implementation weaknesses.
