What are the most effective ways to prevent insecure direct object references in web applications?
Insecure direct object references (IDOR) are a common web security vulnerability that allow attackers to access or manipulate data that they are not authorized to. For example, if a web application uses a user ID as a parameter in the URL to display a profile page, an attacker could change the ID and view another user's profile. IDOR can lead to data breaches, identity theft, fraud, or unauthorized actions. In this article, you will learn what are the most effective ways to prevent IDOR in web applications.
