A Django-based vulnerable lab built to simulate real-world IDOR scenarios — not just textbook examples.
If you've spent any time in Bug Bounty hunting or penetration testing, you've probably encountered the same frustrating cycle:
- Find a vulnerable lab online.
- Get excited.
- Realize it's overly simplistic, outdated, or completely divorced from reality.
The problem with most vulnerable-by-design applications is that they teach vulnerabilities in isolation. You learn what an IDOR is, sure — but not how it manifests inside a messy, multi-user, production-like application with actual business logic.
That's exactly why IDOR Lab exists.
What is IDOR Lab?
IDOR Lab is an open-source training platform built with Django and TailwindCSS. It’s designed specifically for security researchers, Bug Bounty hunters, and developers who want to understand Insecure Direct Object Reference (IDOR) vulnerabilities at a deeper level.
But here's what sets it apart: it doesn't stop at "change the ID in the URL."
This lab simulates an e-commerce environment — product pages, order histories, invoices, user dashboards — and injects realistic authorization flaws throughout. The result is a playground that feels closer to a real target than a classroom exercise.
Why Most Labs Fall Short
Let's be honest: most vulnerable labs are built by security people, not product people. They lack:
- Realistic user flows
- Multi-user data separation
- Business logic complexity
- Modern front-end design
IDOR Lab flips that. The interface is clean and responsive. The database relationships mimic real-world patterns. The seed command generates fake users, orders, and invoices — so you're not hunting bugs in an empty application.
What You'll Practice
The lab intentionally includes:
- Object ownership mistakes
- Weak authorization checks
- Predictable identifiers
- File access vulnerabilities
- Multi-step workflows ripe for abuse
And this is just the beginning. The roadmap includes:
- API-based IDOR challenges (Django REST Framework)
- UUID vs Integer ID comparisons
- Mass assignment and GraphQL challenges
- Role-based access control flaws
- Secure vs Vulnerable mode toggles
- Docker support and CI/CD integration
The creator's philosophy is clear: this isn't just about learning IDOR. It's about training your eye for real attack surfaces, not just toy examples.
Who Is This For?
- Bug Bounty beginners tired of labs that feel nothing like production.
- Experienced hunters looking for a quick, realistic warm-up environment.
- Developers who want to understand how authorization flaws happen — and how to prevent them.
- CTF players who want a more practical, less puzzle-like challenge.
Quick Start
git clone https://github.com/cyberjsonp/idor-django-lab.git
cd idor-django-lab
python -m venv venv
source venv/bin/activate # or venv\Scripts\activate on Windows
pip install -r requirements.txt
python manage.py migrate
python manage.py seed_lab
python manage.py runserver
Within minutes, you have a fully populated vulnerable application running locally.
A Note on Ethics
This project is strictly for education and ethical research. It contains intentionally vulnerable code — do not deploy it publicly or use it for anything outside of a controlled learning environment.
Final Thoughts
The gap between "knowing about IDOR" and "finding IDOR in the wild" is massive. IDOR Lab is one of the few projects actively trying to close that gap by simulating the chaos, complexity, and subtlety of real applications.
If you're serious about Bug Bounty, this one belongs in your toolbox.
