jwt-library-flaws

What problem does it solve?

This Skill helps identify and prevent critical security vulnerabilities within the implementation of JSON Web Token (JWT) libraries themselves, rather than just how they are used.

Core Features & Use Cases

• Vulnerability Detection: Pinpoints common flaws in JWT verification logic, such as algorithm confusion, improper handling of the 'none' algorithm, and insecure key management.
• Code Review Aid: Assists developers and security auditors in systematically checking JWT library code for known weaknesses.
• Use Case: When reviewing a new authentication library that uses JWTs, use this Skill to ensure its token verification logic is robust against common bypass techniques.

Quick Start

Analyze the provided JWT library code for implementation flaws.
