Claude Code issues we find in JavaScript projects
Problems specific to Claude Code's code generation patterns when building JavaScript apps.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
JavaScript security review issues we check for
Security Review-specific JavaScript problems that need attention before production.
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.
