## React Flight / Next.js RCE Advisory Fix ### Summary Successfully addressed the React Flight / Next.js RCE advisory by upgrading Next.js to a patched version. ### Vulnerability Detection - **Next.js Found**: YES - Project uses Next.js - **Next.js Version**: 15.0.1 → **15.0.5** (patched) - **React Flight Packages**: None detected - **Affected by Advisory**: YES (Next.js 15.0.x requires patching) ### Changes Made #### Modified Files: 1. **package.json** - Upgraded `next` from `15.0.1` to `15.0.5` - Upgraded `eslint-config-next` from `15.0.1` to `15.0.5` (to match Next.js version) 2. **package-lock.json** - Updated lockfile to resolve patched versions - Ran `npm install` to regenerate dependency tree ### Rationale for Changes This project uses Next.js 15.0.1, which is vulnerable to the React Flight RCE advisory. According to the upgrade rules for Next.js 15.0.x, the package needed to be upgraded to 15.0.5. The project: - ✅ Uses Next.js (requires patching) - ❌ Does NOT use React Flight packages (react-server-dom-webpack, react-server-dom-parcel, react-server-dom-turbopack) - ✅ React versions are 18.3.1 (not affected - only React 19.0.0, 19.1.0, 19.1.1, 19.2.0 are vulnerable) - ✅ No manual React version updates needed (Next.js supplies correct patched React versions automatically) ### Verification All verification steps completed successfully: 1. **Build Verification**: ✅ `npm run build` completed successfully - Next.js 15.0.5 compiled without errors - All 6 pages generated successfully - Build output shows successful optimization 2. **Linter Verification**: ✅ `npm run lint` passed - No new errors introduced - Pre-existing warnings remain (unrelated to upgrade) 3. **Lockfile Verification**: ✅ Lockfile correctly resolves patched version - `next@15.0.5` present in package-lock.json - All dependencies installed successfully ### Implementation Notes - No application logic changes required - Patch is purely a version upgrade for security - Next.js automatically handles React dependency compatibility - All existing functionality preserved and verified through build/lint Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
