react2shell-scanner

react2shell-scanner is a security research tool designed to detect and demonstrate potentially dangerous patterns in React-based codebases that could lead to command injection, unsafe environment handling, insecure API usage, or other high-impact vulnerabilities.

This project is meant only for security auditing, code review, static analysis research, and secure development training.

🎯 Purpose of This Project

react2shell-scanner aims to:

• help developers understand how dangerous patterns can appear in React codebases,
• identify insecure JavaScript usage that could escalate into shell command execution,
• support secure coding practices and encourage remediation of risky patterns,
• serve as a learning resource for application security researchers,
• provide examples of static analysis techniques for JavaScript/React.

This project does not exploit vulnerabilities — it only analyzes and reports suspicious patterns.

🛠 Features

• Static detection of:
  • unsafe string interpolation in command-like contexts,
  • risky environment variable handling in React apps,
  • dangerous serialization patterns,
  • insecure client → server communication patterns,
  • suspicious dynamic function usage.

---

🚀 Quick Start

git clone https://github.com/talentte/react2shell-scanner.git

cd react2shell-scanner

pip install -r requirements.txt

python react2shell.py.py

✔️ Recommended Best Practices (High-Level)

Avoid passing untrusted input into shell-like contexts (even indirectly).

Avoid dynamic function construction (e.g., new Function()).

Do not expose sensitive configuration to the client side.

Validate all input that reaches the server.

Use static analysis, linting, and dependency auditing tools.

Keep React, Node.js, and all dependencies updated.
