React Security

Secure your React application

React apps are vulnerable to XSS via dangerouslySetInnerHTML, prototype pollution from libraries, and sensitive data exposed in JS bundles. ShipSafer scans the deployed app for security weaknesses.

What ShipSafer checks for React

  • CSP headers blocking inline scripts
  • XSS-prone response headers
  • Cookie security attributes
  • SSL/TLS configuration
  • HTTP security headers
  • Third-party dependency vulnerabilities
