# React Flight / Next.js RCE Advisory Fix ## Summary Successfully addressed the React Flight / Next.js RCE advisory (CVE-2024-50388) in the sync-rover project. ## Detection Results - **Project Type**: Next.js application - **Affected Package**: `next` (was at 15.5.4, a vulnerable version) - **Not Affected**: - Project does not use any React Flight packages (`react-server-dom-webpack`, `react-server-dom-parcel`, or `react-server-dom-turbopack`) - React and React-DOM do not require manual updates for Next.js projects; Next.js handles this automatically ## Changes Made ### 1. Updated Next.js Package - **From**: `next@15.5.4` (vulnerable) - **To**: `next@15.5.7` (patched version for 15.5.x branch) - Also updated related packages: - `eslint-config-next`: 15.5.4 → 15.5.7 ### 2. Files Modified 1. **package.json**: Updated version specifiers for `next` and `eslint-config-next` 2. **bun.lock**: Updated lockfile to resolve to patched versions - All next-related packages now resolve to 15.5.7 - All @swc packages and other Next.js dependencies updated accordingly ## Verification ### Build Status ✅ **Build Successful**: `next build --turbopack` completed successfully ### Package Resolution ✅ **Lockfile Verification**: bun.lock now correctly resolves to: - `next@15.5.7` - `eslint-config-next@15.5.7` - All corresponding `@next/swc-*` packages at 15.5.7 ### Linting ✅ **No New Issues**: The existing 2 pre-existing linting warnings remain unchanged: - `'role' is assigned a value but never used` (pre-existing) - React Hook useEffect missing dependencies (pre-existing) ## Security Impact This update patches the RCE vulnerability in Next.js that could allow remote code execution through specially crafted requests. The project is now running the patched version 15.5.7. ## Notes - The project uses bun as its package manager, which was automatically installed and used for dependency resolution - No application code changes were needed - No breaking changes introduced; the build and linter produce the same output (except for the security fix) Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
