## React Flight / Next.js RCE Advisory Update ### Summary Updated the Samurai repository to address the React Flight / Next.js RCE advisory by upgrading Next.js to a patched version. ### Analysis **Project Status:** ✅ Affected by the advisory The project was identified as affected because it uses: - **Next.js 15.3.4** - This is a vulnerable version that requires patching The project does NOT use any React Flight / React Server Components packages: - ✗ `react-server-dom-webpack` - Not used - ✗ `react-server-dom-parcel` - Not used - ✗ `react-server-dom-turbopack` - Not used Therefore, React and React DOM versions did not require manual updates (Next.js will supply patched versions automatically). ### Changes Made **Files Modified:** 1. `package.json` - Updated dependencies - Upgraded `next` from `15.3.4` → `15.3.6` - Upgraded `eslint-config-next` from `15.3.4` → `15.3.6` 2. `package-lock.json` - Updated lockfile to reflect patched versions ### Verification ✅ Dependencies successfully installed - npm install completed successfully - 617 packages added with correct patched versions - Lockfile correctly shows `next@15.3.6` as resolved version - Node modules contain exact version: `15.3.6` ### Implementation Notes - Only the `next` dependency was modified (as per the advisory rules for 15.x versions) - The upgrade from 15.3.4 → 15.3.6 is a patch-level change within the same minor version - React and React DOM versions remain at 19.0.0 (Next.js will handle these automatically) - The eslint-config-next was also updated to match for consistency - Build system correctly recognizes the patched Next.js version (Next.js 15.3.6 confirmed) ### Advisory Context This update addresses CVE-2024-58155, a Remote Code Execution vulnerability in Next.js and React Flight packages. The vulnerability affects: - Next.js 16.x versions < 16.0.7 - Next.js 15.x versions < the respective minor patch - React Server Components packages with vulnerable React dependencies Upgrade rule applied: Next.js 15.3.x → 15.3.6 ✓ Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
