Security Review for your JavaScript project
Expert security review for JavaScript applications. We find and fix JavaScript-specific security issues that affect production apps. From $19.
JavaScript security review issues we find
Common security review problems specific to JavaScript applications.
Prototype pollution
AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.
eval() and dynamic code execution
AI tools sometimes use eval(), new Function(), or setTimeout with strings to handle dynamic logic, opening severe code injection vulnerabilities.
What our JavaScript 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Known CVEs in your npm/pip packages, outdated libraries, and supply chain risks.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.
