Fix Improper Assets Management in Blitz.js

// Directory Structure:
// app/
// public/
//   ├── images/
//   ├── .env.production  <-- CRITICAL LEAK: Exposed to / .env.production
//   ├── schema.prisma    <-- LEAK: Database architecture exposed
//   └── internal_api.pdf <-- LEAK: Internal docs
// blitz.config.ts
const config = {
// No headers or security middleware protecting the public folder
// Everything inside /public is served with a 200 OK by default
};
export default config;

// 1. Move all sensitive files to the root directory and update .gitignore
// .gitignore
// .env*
// schema.prisma
// 2. Implement a custom middleware to restrict access to specific static paths if necessary
// src/middleware.ts
import { blitzMiddleware } from ”./blitz-server”
export default blitzMiddleware(async (req, res, next) => {
const { pathname } = new URL(req.url || "", “http://localhost”)
if (pathname.startsWith(“/protected-assets/”) && !req.session.userId) {
res.statusCode = 403
res.end(“Access Denied”)
return
}
return next()
})
// 3. Set Security Headers in blitz.config.ts
const config = {
async headers() {
return [
{
source: ”/(.*)”,
headers: [
{ key: “X-Content-Type-Options”, value: “nosniff” },
{ key: “Content-Security-Policy”, value: “default-src ‘self’;” }
],
},
]
},
};
