Security Scanner forBolt.new Apps
Bolt.new ships full-stack apps in seconds. But unauthenticated API routes and exposed secrets mean your app could be compromised in seconds too. ShipSafe finds what Bolt's AI missed.
The Security Cost of Instant Full-Stack Apps
Bolt.new is impressive. You describe what you want, and it generates a complete application with frontend, backend, and database in one shot. The problem is that the AI skips the boring but critical security plumbing that separates a demo from a production app.
Every API route Bolt creates is a potential entry point for attackers. Without auth checks, anyone can call them. Without input validation, malicious payloads flow straight through. And because Bolt uses Vite, any secret prefixed with VITE_ ends up in your users' browsers.
We've documented the specific patterns in our Bolt.new security guide and the vulnerabilities by platform reference.
Common Vulnerabilities in Bolt.new Projects
These patterns appear in the vast majority of Bolt.new-generated applications we analyze.
Unauthenticated API Routes
CriticalBolt.new generates API endpoints that handle data mutations (create, update, delete) without verifying that the caller is logged in. Anyone who discovers the route can call it directly with curl or Postman, bypassing your entire frontend.
Secrets in VITE_ Environment Variables
CriticalBolt.new uses Vite as its build tool, and any env var prefixed with VITE_ gets bundled into the frontend JavaScript. The AI frequently puts API keys, database URLs, and webhook secrets behind VITE_ prefixes, making them visible to anyone who opens browser DevTools.
Missing Input Validation
HighBolt-generated endpoints typically trust all incoming data. There is no schema validation, no type checking, and no sanitization. Malformed payloads, oversized inputs, and injection attempts pass straight through to your database.
No CSRF Protection
HighBolt.new does not generate CSRF tokens or SameSite cookie configurations. State-changing requests can be triggered from any website by embedding a hidden form, letting attackers perform actions on behalf of logged-in users.
How ShipSafe Secures Your Bolt.new App
Connect Your Bolt.new Project
Bolt can push your project to GitHub in a couple of clicks — connect that repo. ShipSafe recognizes Bolt.new's Vite-based project structure and understands how it handles routing and env vars.
Full-Stack Security Analysis
ShipSafe scans both frontend and backend code. It maps every API route, checks for auth middleware, validates env var scoping, and tests for CSRF and input validation gaps.
