How I Found 4 IDORs in the Same Target🔥

A Real-World Case Study

Introduction

Finding Insecure Direct Object References (IDORs) is like striking gold for ethical hackers and bug bounty hunters. IDOR vulnerabilities allow unauthorized users to access sensitive information simply by modifying parameters. In this blog, I’ll share how I discovered four IDOR vulnerabilities in the same target, step by step, with real examples. 🚀

What is an IDOR Vulnerability? 🛡️

IDOR (Insecure Direct Object Reference) is a security flaw that occurs when an application does not properly validate user access to objects. This allows attackers to manipulate object identifiers in requests to access unauthorized data.

Why IDORs are Dangerous?

• Unauthorized access to sensitive data
• Possible privilege escalation
• Leakage of user information
• Potential business risks
