To audit Next.js App Router security, scan app/**/actions.ts files to verify authentication, authorization, and input validation for server actions. Automated pattern checks detect missing protections and provide recommended fixes to prevent unauthorized access.

Checking Next.js environment variable exposure involves scanning for NEXT_PUBLIC_ variables and inlined env values in client bundles. Automated pattern checks identify these exposed values and provide guidance to reduce data leakage risks.

Ensuring Next.js middleware matcher coverage requires reviewing your middleware configuration to verify it includes all protected paths. Automated checks analyze matcher patterns and security header configurations to enforce route protections.

Yes, the Next.js security audit checks API route protections by scanning app/api/**/route.ts files. It verifies authentication and input validation patterns across your API routes, identifying vulnerabilities and recommending fixes to mitigate unauthorized access.

Yes, you need ripgrep installed as a dependency to run the automated security scan scripts. The tool uses ripgrep to efficiently perform pattern checks across your Next.js project files for environment variables, server actions, and middleware configurations.

Configuring Next.js security headers requires reviewing your middleware and response configurations to ensure necessary headers are set. The audit checks your header configurations and provides guidance to align with recommended security practices.
