## React Flight / Next.js RCE Advisory - Security Update Report ### Summary Updated MagiCV repository to address the React Flight / Next.js RCE advisory (CVE-2024-52219 / CVE-2024-52220). The project used an affected version of Next.js and required security updates. ### Vulnerability Assessment #### 1. Affected Package Detection - ✅ **Next.js Present**: Yes, was using flexible version constraint `>=15.5.4` - ❌ **React Flight Packages**: No (not affected by React Flight-specific vulnerability) - `react-server-dom-webpack`: Not present - `react-server-dom-parcel`: Not present - `react-server-dom-turbopack`: Not present #### 2. Initial Vulnerability **Problem**: The project had `"next": ">=15.5.4"` in package.json, which could resolve to: - Next.js 16.0.0 (VULNERABLE - not patched) - The lockfile showed resolution to 16.0.0, which is outside the patched version range **Why This Matters**: - The React Flight / Next.js RCE advisory affects Next.js versions - Version 15.5.4 and 15.5.5 are vulnerable - Version 15.5.6+ are patched - The loose version constraint allowed resolution to 16.0.0, which is outside the supported minor version for this project ### Changes Made #### Modified Files: 1. **package.json** - Changed: `"next": ">=15.5.4"` → `"next": "15.5.7"` - Reason: Pinned to the patched version for the 15.5.x minor version 2. **pnpm-lock.yaml** - Updated resolution to use Next.js 15.5.7 (was resolving to 16.0.0) - All dependent packages properly resolved with Next.js 15.5.7 #### Created Files: - **.vade-report**: This compliance report ### Final Dependency Versions **Next.js Compliance** (Section 2 of advisory): - Required: 15.5.7 (for 15.5.x minor version) - Implemented: ✅ 15.5.7 (pinned version) **React/React-DOM Versions**: - React: ^19.0.0 → Resolves to 19.2.0 (safe version) ✅ - React-DOM: ^19.0.0 → Resolves to 19.2.0 (safe version) ✅ - Managed by Next.js automatically (not manually upgraded) **React Flight Packages**: - No vulnerable packages present (not affected) ### Verification **Build Status**: ✅ Project builds successfully with patched versions - pnpm-lock.yaml correctly resolves to next@15.5.7 - React dependencies resolve to safe versions (19.2.0) - All dependent packages work with patched Next.js version **Lockfile Verification**: ✅ Confirmed patched version resolution ``` next@15.5.7: (installed) react@19.2.0: (installed) react-dom@19.2.0: (installed) ``` ### Compliance Checklist - ✅ Project uses Next.js 15.5.x - ✅ Upgraded to patched version 15.5.7 - ✅ No manual React/React-DOM upgrades needed - ✅ No React Flight packages affected - ✅ Lockfile updated with correct patched versions - ✅ Build verification successful ### Conclusion MagiCV has been successfully updated to address the React Flight / Next.js RCE advisory. The Next.js version is now pinned to 15.5.7 (the required patched version for the 15.5.x minor), and the lockfile correctly reflects this version with all compatible dependencies. The project is now fully compliant with the security advisory requirements. Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
