In this lab, we delve into the vulnerabilities associated with Insecure Direct Object References (IDOR). By examining a sample web application, you will see how incrementing numerical parameters in URLs can allow unauthorized access to other users' information. This lab emphasizes the need for robust security measures, specifically in the context of user authorization checks.

The accompanying video provides a detailed source code review for the challenge authorization 02, part of the essential badge. It walks through the code from the initialization of libraries to the configuration of database connections and user sessions. The video highlights the critical importance of checking user permissions at every stage of data access and manipulation. These checks ensure that each user can only access their own data, thus preventing unauthorized access and potential data breaches.
