React Flight / Next.js RCE Advisory Security Fix SUMMARY: Updated the project to address the React Flight / Next.js RCE advisory. The project was already using Next.js and required a security update. DETECTION RESULTS: ✅ Project is affected by advisory: - Next.js detected at version 16.0.1 (16.x range) - No React Flight packages (react-server-dom-*) found - React versions: 19.2.0 (safe version) CHANGES IMPLEMENTED: Modified: package.json - Updated next from 16.0.1 to 16.0.7 (patched version for 16.x) VERIFICATION: ✓ Dependencies resolved successfully - npm install completed without errors ✓ Lockfile updated correctly - package-lock.json shows next@16.0.7 ✓ No vulnerability warnings in npm audit ✓ All dependent packages (@next/env, @next/swc-*) updated to 16.0.7 BUILD STATUS: The Next.js build compilation completes successfully. There is a pre-existing TypeScript type error in ./app/recipes/[slug]/comments.tsx (unrelated to the security fix) that prevents the full build from completing. This is an application-level issue, not a dependency-related issue, and falls outside the scope of dependency security patching. TECHNICAL NOTES: - The project uses npm as the package manager (package-lock.json) - Only one package.json file found (no monorepo structure) - React and React DOM did not require updates for this Next.js patch - The advisory fix ensures Next.js 16.0.7 includes security patches to prevent RCE vulnerabilities in React Flight / Server Component handling AFFECTED VERSIONS FIXED: - Next.js 16.0.1 → 16.0.7 (includes RCE fix for React Flight/RSC vulnerability) Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
