The vulnerability also affects standalone React Flight packages when using vulnerable React versions. ### Project Assessment This project uses Next.js and was vulnerable. The following changes were made to apply the security patch: ### Changes Made **Modified package.json files:** 1. **nextjs/package.json** - `next`: 15.3.4 → 15.3.6 (patched version) - `eslint-config-next`: 15.3.4 → 15.3.6 (aligned with Next.js version) 2. **ui/package.json** - `next`: ^15.3.0 → 15.3.6 (pinned to patched version) 3. **package/package.json** - `next`: ^15.2.3 → 15.2.6 (patched version) - `react-dom`: ^19.1.0 → 19.1.2 (patched React version for compatibility) 4. **pnpm-lock.yaml** - Updated lockfile to resolve all patched versions correctly **Generated changes (from build):** - ui/public/checkout-dialog.json - regenerated by shadcn build - ui/public/pricing-table.json - regenerated by shadcn build ### Verification ✅ **Lockfile Resolution:** Verified that pnpm-lock.yaml contains the following patched versions: - next@15.3.6 (resolution: sha512-oI6D1zbbsh6JzzZFDCSHnnx6Qpvd1fSkVJu/5d8uluqnxzuoqtodVZjYvNovooznUq8udSAiKp7MbwlfZ8Gm6w==) - next@15.2.6 (resolution: sha512-DIKFctUpZoCq5ok2ztVU+PqhWsbiqM9xNP7rHL2cAp29NQcmDp7Y6JnBBhHRbFt4bCsCZigj6uh+/Gwh2158Wg==) ✅ **Build Verification:** UI project build completed successfully with Next.js 15.3.6 ### Risk Assessment - No React Flight packages (`react-server-dom-*`) are used in this project - All Next.js versions are now at the minimum patched versions required by the advisory - React versions are compatible with the patched Next.js versions ### Implementation Details - Followed the advisory upgrade rules for each Next.js minor version - Did not upgrade across major versions - Updated lockfiles using pnpm install to ensure consistency - Verified no vulnerable dependency versions remain in the resolved dependency tree Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
