Data Leak Issue

Issue Description

This is a critical issue notified by @Ajeyakrishna-k. This backend project has 3 endpoints - verification, profile, and health. The purpose of the profile API endpoint is to provide details of the owner like company, phone number, etc. To protect this API, we are receiving a bearer token, if the token is correct then it returns profile data. The issue is that one can generate that token from the verification endpoint easily by sending a salt.

Reproducibility

• This issue is reproducible
• This issue is not reproducible

Steps to Reproduce

1. Try calling the verification endpoint with a salt, it will return a hash.
2. Send that hash as a bearer token while calling the profile endpoint, you will get the profile data.
