[!WARNING] This application contains intentional security flaws and must never be deployed in a production environment.

Features

• Intentionally vulnerable e-commerce app (XSS, CSRF, IDOR, JWT attacks, path traversal, SQL injection, and more)
• Built with Next.js, React, Prisma, and SQLite
• REST API with documented attack vectors
• 35 CTF challenges across 11 chapters, laid out as a structured learning roadmap
• Vulnerability documentation and community walkthroughs for each challenge
• Automated tests that verify exploits still work (PRs that accidentally fix a vuln will fail CI)

Why OopsSec Store?

OopsSec Store is the only intentionally vulnerable web application built with Next.js and React. The stack you'll actually encounter in production. And the AI-era attack surface is part of the core curriculum, not an afterthought: prompt injection, MCP tool poisoning, AI coding-agent backdoors, and an npm supply-chain attack chain simulated end to end.

Installation

Quick start

npx create-oss-store my-ctf-lab
cd my-ctf-lab
npm start

Then open http://localhost:3000 in your browser.

Manual setup

Clone the repo and run the setup script:

git clone https://github.com/kOaDT/oss-oopssec-store.git
cd oss-oopssec-store
npm run setup

This creates the .env file, installs dependencies, sets up the SQLite database, seeds it with CTF flags, and starts the app on port 3000.

Docker

No Node.js required. Just Docker.

From Docker Hub (quickest)

docker run -p 3000:3000 leogra/oss-oopssec-store

To persist data across restarts:

docker run -p 3000:3000 -v oss-data:/app/data leogra/oss-oopssec-store

From source (Docker Compose)

git clone https://github.com/kOaDT/oss-oopssec-store.git
cd oss-oopssec-store
docker compose up -d

Or using the npm helper scripts:

npm run docker:up       # Start in background (builds image on first run)
npm run docker:logs     # Follow container logs
npm run docker:down     # Stop the container
npm run docker:reset    # Wipe data and restart fresh

The database initializes on first start. Data persists across restarts via Docker named volumes. To reset everything (flag progress, users, uploads), run npm run docker:reset.

Hall of fame

Testing

The project includes security regression tests that make sure all exploit chains and flags still work. These tests deliberately validate insecure behavior. They run on every PR, so if you accidentally patch a vulnerability, CI will catch it.

Running tests

# Unit tests (utility functions: MD5 hashing, JWT, input filters)
npm run test:unit

# API exploitation tests (requires a running server)
npm run test:api

# E2E exploitation tests (requires a running server)
npm run test:e2e

# Open Cypress interactive mode
npm run test:e2e:open

# All tests
npm run test:ci
