Security Scanner for Bolt.new Apps

Bolt.new generates deployable apps from natural language prompts in seconds. The speed is incredible, but the generated code frequently ships API keys in client bundles, omits security headers, and creates XSS attack surfaces. SimplyScan catches these issues instantly.

Top Vulnerabilities in Bolt.new Apps

• API Keys Bundled in Client JavaScript · Bolt.new apps frequently include third-party API keys (Stripe, OpenAI, Firebase) directly in frontend code, making them visible to anyone who opens browser DevTools.
• Missing Security Headers · Generated apps typically lack Content-Security-Policy, X-Frame-Options, and HSTS headers · leaving them vulnerable to clickjacking, XSS, and protocol downgrade attacks.
• XSS Vulnerabilities · AI-generated React code may use dangerouslySetInnerHTML or unsanitized URL parameters, creating cross-site scripting attack vectors.
• No CORS Restrictions · Bolt.new APIs often ship with Access-Control-Allow-Origin: *, allowing any website to make authenticated requests to your backend.
• Unprotected API Endpoints · Backend routes generated by AI may lack authentication middleware, allowing unauthenticated access to sensitive operations.
