## React Flight / Next.js RCE Advisory - Patch Implementation Report ### Project Status: PATCHED ✅ The perler-beads repository has been successfully updated to address the React Flight / Next.js RCE advisory. Vulnerable dependencies have been patched to secure versions. ### Changes Made #### 1. Next.js Version Update - **File:** `package.json` - **Changed:** `"next": "15.3.1"` → `"next": "15.3.6"` - **Reason:** Next.js 15.3.1 is affected by the RCE vulnerability. Per the advisory, Next.js 15.3.x versions require patching to 15.3.6. - **Status:** ✅ Patched #### 2. ESLint Config Update - **File:** `package.json` (devDependencies) - **Changed:** `"eslint-config-next": "15.3.1"` → `"eslint-config-next": "15.3.6"` - **Reason:** Must match the Next.js version for consistency - **Status:** ✅ Updated #### 3. Lockfile Update - **File:** `package-lock.json` - **Details:** Updated all Next.js dependencies from 15.3.1 to 15.3.6 including: - `next` package (15.3.1 → 15.3.6) - All `@next/*` sub-packages updated to match - **Status:** ✅ Updated ### Vulnerability Assessment **Affected Packages Detected:** - ✅ **Next.js:** 15.3.1 (affected) → 15.3.6 (patched) - ❌ **React Flight Packages:** Not used in this project - `react-server-dom-webpack` - NOT present - `react-server-dom-parcel` - NOT present - `react-server-dom-turbopack` - NOT present **React & React-DOM:** - Current: `^19.0.0` (as specified in package.json) - Lockfile resolves to: `19.1.0` - **Action:** No changes made - per advisory instructions, React versions in Next.js projects are not manually updated. Next.js 15.3.6 handles React dependency management automatically. - **Status:** ✅ Appropriate for Next.js 15.3.6 ### Patch Verification #### Build Test ``` > next build ✓ Compiled successfully in 2000ms ✓ Generating static pages (7/7) Route (app) build status: SUCCESS ``` #### Linter Test ``` > next lint ✓ No ESLint warnings or errors ``` #### Dependency Resolution - Next.js in node_modules: 15.3.6 ✅ - Next.js in package-lock.json: 15.3.6 ✅ - Next.js in package.json: 15.3.6 ✅ ### Files Modified 1. `package.json` - Updated Next.js and eslint-config-next versions 2. `package-lock.json` - Updated lockfile with resolved patched versions ### Files Not Modified - `react` and `react-dom` package specifications remain at `^19.0.0` (correct per advisory) - All application code remains unchanged - All other dependencies remain unchanged ### Verification Summary ✅ **Project is vulnerable** - Next.js 15.3.1 was affected ✅ **Patches applied** - Updated to Next.js 15.3.6 ✅ **Dependencies resolve** - Lockfile confirms 15.3.6 is installed ✅ **Build succeeds** - Next.js build completes without errors ✅ **Linter passes** - No new lint issues introduced ✅ **No breaking changes** - Application code unchanged ### Conclusion The perler-beads repository has been successfully patched for the React Flight / Next.js RCE advisory: - Vulnerable Next.js 15.3.1 upgraded to secure 15.3.6 - All supporting dependencies updated to match - Build verification passed - No additional code changes required The project is now secure against this vulnerability. --- *Implementation completed per React Flight / Next.js RCE advisory requirements* Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
