SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires dompurify, content-security-policy, csrf, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill ensures the security of React applications by preventing XSS attacks, securing authentication flows, and hardening application boundaries.

Core Features & Use Cases

  • XSS Prevention: Sanitizes HTML and handles JavaScript protocols securely.
  • Secure Authentication: Stores JWT/Sessions securely and uses Content Security Policy (CSP).
  • Harden Boundaries: Implements CSRF protection, input sanitization, and security headers.
  • Use Case: Before deploying a new React app, use this Skill to scan and harden the app against common security vulnerabilities.

Quick Start

Use the react-security skill to scan a React application for XSS vulnerabilities and harden authentication.

Frequently Asked Questions about react-security

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent XSS vulnerabilities in a React application?▼

Prevent XSS vulnerabilities in a React application by sanitizing HTML and securing JavaScript protocols using DOMPurify. This approach scans your app to mitigate injection risks and harden boundaries before deployment.

What is the best way to secure authentication flows in React?▼

Secure authentication flows in React by storing JWT and sessions securely while enforcing a strict Content Security Policy. This combination protects user credentials and hardens application boundaries against unauthorized access.

How do I implement CSRF protection for JavaScript based web applications?▼

Implement CSRF protection for JavaScript based web applications by configuring CSRF tokens alongside input sanitization and security headers. This ensures requests are verified and application boundaries remain hardened.

Do I need to configure Content Security Policy and DOMPurify to harden React app security?▼

Yes, hardening React app security requires proper configuration of DOMPurify, Content Security Policy, and CSRF tokens. These dependencies are necessary to scan for vulnerabilities and secure authentication effectively.

When should I scan my React app for security vulnerabilities?▼

Scan your React app for security vulnerabilities before deploying a new application or release. This process identifies XSS flaws and missing security headers, ensuring authentication flows and boundaries are fully hardened.
