AI Code Security Scanner for TypeScript

TypeScript projects — especially those using React, Next.js, and modern full-stack frameworks — are heavily targeted by AI code assistants. While TypeScript's type system catches some errors, it cannot prevent security vulnerabilities like XSS through dangerouslySetInnerHTML, SQL injection in Prisma raw queries, or hardcoded secrets. AI tools frequently generate Next.js API routes with overly permissive CORS and insecure JWT configurations.

What CodeShield detects in TypeScript files

CodeShield performs deep static analysis on .ts/.tsx files to detect OWASP Top 10 vulnerabilities, exposed secrets, quantum-vulnerable cryptography, and insecure coding patterns specific to the TypeScript ecosystem.

dangerouslySetInnerHTML with unsanitized data

Prisma $queryRaw and $executeRaw with interpolation

TypeORM raw query string concatenation

Hardcoded JWT_SECRET and API keys in .ts files

Next.js API routes with CORS wildcard headers

crypto.createHash with MD5/SHA-1

RSA and ECDSA key generation via Node.js crypto

Zod/Yup schema bypasses in form handling

Server actions without proper input validation

tRPC procedures missing authorization checks

AI tools that generate TypeScript code

The following AI coding assistants actively generate TypeScript code and are known to introduce the vulnerability patterns listed above:

These tools produce correct code in most cases, but studies show that up to 45% of AI-generated code contains at least one security vulnerability. CodeShield catches what code review misses.
