TypeScript Security Review

Overview

Security review for TypeScript/Node.js applications. Evaluates code against OWASP Top 10, framework-specific patterns, and production-readiness criteria. Findings are classified by severity (Critical, High, Medium, Low) with remediation examples. Delegates to the typescript-security-expert agent for deep analysis.

When to Use

• Performing security audits on TypeScript/Node.js codebases
• Reviewing authentication and authorization implementations (JWT, OAuth2, Passport.js)
• Checking for common vulnerabilities (XSS, injection, CSRF, path traversal)
• Validating input validation and sanitization logic
• Reviewing dependency security (npm audit, known CVEs)
• Checking secrets management and environment variable handling
• Assessing API security (rate limiting, CORS, security headers)
• Reviewing Express, NestJS, or Next.js security configurations
• Before deploying to production or after significant code changes
• Compliance checks (GDPR, HIPAA, SOC2 data handling requirements)
