Looking for an Expert to Audit API for JWT Vulnerabilities

Job ID: 38999035

Budget: $30 – $250 USD

Hi there!

I am looking for a cybersecurity specialist or an experienced developer to audit an API that uses JSON Web Tokens (JWT) and identify any potential vulnerabilities. The goal is to ensure that the API is secure and protected against attacks.

Requirements:

- Proven experience in auditing and testing the security of APIs.
- Strong understanding of JWT implementation and security best practices.
- Ability to identify common vulnerabilities such as:
- Token forgery attacks;
- Missing or improper signature verification;
- Misconfigured algorithms (e.g., HS256 vs RS256);
- Exposure of sensitive data in the token payload.
- Ability to recommend solutions for any identified vulnerabilities.

If you have the skills and expertise to help secure my API, I’d love to hear from you. Please include examples of similar projects you’ve worked on when applying.

Looking forward to your proposals!
