# React Flight / Next.js RCE Advisory - Impact Assessment

## Project Status: NOT AFFECTED

After a comprehensive analysis of the headkit-storefront repository, this project **does not require any changes** in response to the React Flight / Next.js RCE advisory.

## Vulnerability Assessment

### Packages Checked:
1. **Next.js**: Version 16.0.7 ✅
   - The project uses `next@16.0.7`, which is the patched version for the 16.x release
   - No action needed

2. **React Flight / React Server Components**:
   - `react-server-dom-webpack`: NOT present
   - `react-server-dom-parcel`: NOT present
   - `react-server-dom-turbopack`: NOT present
   - No action needed

3. **React and React DOM**: Versions 19.2.0 ✅
   - While the project uses React 19.2.0 and React DOM 19.2.0, these versions are NOT vulnerable themselves
   - The vulnerability only affects React Flight packages (react-server-dom-*), which are not used in this project
   - No action needed

## Conclusion

The headkit-storefront repository is **not affected** by the React Flight / Next.js RCE advisory because:

1. ✅ Next.js is already at a patched version (16.0.7)
2. ✅ No vulnerable React Flight packages are installed
3. ✅ React and React DOM themselves are not vulnerable to this advisory

**No code changes are required.**
