# React Flight / Next.js RCE Advisory - Vulnerability Remediation ## Summary The PodCastify project has been assessed and remediated against the React Flight / Next.js RCE advisory. The project was using a vulnerable version of Next.js and has been patched to the safe version. ## Vulnerability Assessment & Remediation ### Project Configuration - **Project Type**: Next.js Application - **Main package.json**: ./package.json - **Monorepo Structure**: No (single package.json only) - **Package Manager**: npm ### Affected Packages Analysis #### Next.js - **Previous Version**: `^15.3.3` (vulnerable) - **Current Version**: `15.3.6` (patched) - **Advisory Requirement**: For 15.3.x, upgrade to `15.3.6` - **Status**: ✅ FIXED #### React Flight Packages - **Status**: NOT USED - Checked for: - `react-server-dom-webpack` - NOT FOUND - `react-server-dom-parcel` - NOT FOUND - `react-server-dom-turbopack` - NOT FOUND #### React Dependencies - **react**: `^19.1.0` (compatible with Next.js 15.3.6) - **react-dom**: `^19.1.0` (compatible with Next.js 15.3.6) - **Status**: ✅ COMPATIBLE (No changes required) ## Changes Made ### Files Modified 1. **package.json** - Updated Next.js from `^15.3.3` to `15.3.6` (pinned exact version) - This ensures the patched version is always used and prevents regression to vulnerable versions 2. **package-lock.json** - Updated Next.js and all related dependencies from 15.3.3 to 15.3.6 - Updated dependency checksums and integrity hashes - All transitive dependencies properly resolved to patched versions ### Files Created 1. **.vade-report** - This assessment and remediation report ## Verification ### Build Status - **Next.js Compilation**: ✅ SUCCESSFUL - Compiled without dependency-related errors - All vulnerabilities resolved ### Security Status - ✅ Project is no longer vulnerable to React Flight / Next.js RCE advisory - ✅ All dependencies properly pinned to safe versions - ✅ Lockfile correctly reflects patched versions ## Implementation Details The fix follows the advisory guidance: - Next.js 15.3.x was upgraded to 15.3.6 (the patched version for that minor) - Version is pinned explicitly to prevent future downgrades - React and React-DOM are left unchanged as they are automatically managed by Next.js - No React Flight packages are present, so no additional patches needed ## Conclusion The project is now fully protected against the React Flight / Next.js RCE advisory. The vulnerability has been successfully remediated by upgrading Next.js to version 15.3.6 and updating the lockfile to reflect the patched dependencies.
