## React Flight / Next.js RCE Advisory Patch Implementation

### Summary
Successfully patched the superlend-blogs repository to address the React Flight / Next.js RCE advisory (CVE-2024-XXXXX).

### Vulnerability Detection
The project was identified as affected:
- ✅ **Next.js detected**: `next@15.0.2` (15.0.x minor version)
- ❌ React Flight packages: No `react-server-dom-*` packages found
- This is a Next.js project, not a standalone React Flight app

### Changes Made

#### 1. Updated Dependencies
**File Modified**: `./package.json`
- **Before**: `"next": "15.0.2"`
- **After**: `"next": "15.0.5"`

**Rationale**: According to the React Flight / Next.js RCE advisory:
- Next.js 15.0.x versions require upgrade to `15.0.5` (the patched version for the 15.0 minor series)
- Did NOT manually update `react` or `react-dom` versions, as per the advisory guidance that Next.js will supply the correct patched React dependency versions automatically
- The project's React versions remain at the pre-release RC versions it was using

#### 2. Updated Lockfile
**File Modified**: `./package-lock.json`
- Ran `npm install --legacy-peer-deps` to resolve dependencies
- Verified that the lockfile now reflects `next@15.0.5`
- All dependencies resolved successfully

### Verification
✅ **Build Verification**: Successfully ran `npm run build`
- Next.js compilation: ✓ Compiled successfully
- All 11 static pages generated successfully
- No build errors introduced

### Technical Notes
- The project uses `npm` as its package manager (identified by `package-lock.json`)
- The `--legacy-peer-deps` flag was necessary due to React version peer dependency conflict with the pre-release RC version
- No application code was modified; only dependency versions were updated
- The build completes successfully with the patched Next.js version

### Security Impact
This patch addresses the React Flight RCE vulnerability by upgrading to the patched Next.js version (15.0.5), which includes the necessary security fixes in its dependency resolution.
