You can audit Next.js security vulnerabilities by running a shell script that uses ripgrep for pattern matching to scan for exposed environment variables, unauthenticated Server Actions, and middleware configuration gaps.

To detect exposed environment variables in Next.js, scan the codebase for `NEXT_PUBLIC_` prefixes and review `next.config.js` env settings to identify secrets accidentally exposed to the client.

You can check Next.js Server Actions and API routes for missing authentication by analyzing file patterns to verify that proper authorization and authentication mechanisms are enforced before execution.

Middleware configuration review for Next.js App Router security involves inspecting `middleware.ts` to ensure proper route matching and consistent authentication enforcement across protected application paths.

Yes, you can scan a Next.js project for security misconfigurations before deploying by running an automated directory scan that identifies environment variable exposure and unauthenticated routes.

A Next.js security audit reports missing middleware authentication gaps when pattern analysis of `middleware.ts` detects incomplete route matching or a lack of auth enforcement for protected paths.
