Description

In Simple Exam Reviewer Management System v1.0 the User List function has improper access control that allows lower privileged users to modify user permissions to higher privilege.

Steps to reproduce

Navigate to below mentioned endpoint

"/admin/?page=user/list" 

User will be able to access "User List" and there choose any user and click on action and select edit

Next, change Login type to administrator and save
