Complete Guide to JWT Vulnerabilities: Detection, Exploitation, and WAF Bypass
This article outlines the fundamentals of JSON Web Tokens (JWTs) and common attack methods like key confusion. The researcher explains how to identify weaknesses in validators by examining their response to noisy payloads (Signature Resilience), exploiting poorly implemented libraries that crash instead of returning a 401 error for invalid tokens. JWT structure consists of three parts: Header, Payload, and Signature. Key takeaway: Validate JWTs carefully to avoid security vulnerabilities. #BugBounty #WebSecurity #JSONWebTokens
