Security Review for your Express project
Expert security review for Express applications. We find and fix Express-specific security issues that affect production apps. From $19.
Express security review issues we find
Common security review problems specific to Express applications.
No helmet middleware for security headers
Express apps without the helmet middleware are missing critical security headers like Content-Security-Policy, X-Content-Type-Options, and HSTS, leaving the app vulnerable to common web attacks.
Missing input validation and sanitization
Request body, query params, and URL params used directly without validation. No express-validator, zod, or joi — enabling injection attacks and unexpected crashes.
CORS set to allow all origins
The cors() middleware called with no options, defaulting to allowing requests from any website — a security risk for APIs that handle user data.
No request size limits
express.json() without a size limit allows attackers to send massive payloads that consume all server memory and crash the process.
Secrets hardcoded in source files
Database URIs, API keys, and JWT secrets written directly in the code instead of loaded from environment variables. They end up in Git history.
What our Express security review covers
Authentication & authorization
Login flows, session management, role-based access, token handling, and OAuth integrations.
API security
Input validation, rate limiting, CORS configuration, and protection against injection attacks.
Data exposure
Secrets in source code, environment variable handling, database access controls, and sensitive data in client bundles.
Infrastructure configuration
HTTPS enforcement, security headers, cookie flags, CSP policies, and server hardening.
Dependency vulnerabilities
Known CVEs in your npm/pip packages, outdated libraries, and supply chain risks.
Database security
Row-level security policies, query injection prevention, backup configuration, and access controls.
