Question 1

Can Bolt.new apps be hacked?

Accepted Answer

Yes, Bolt.new generates functional applications quickly, but the AI-generated code often lacks security hardening. Common vulnerabilities include missing authentication on API routes, absence of input sanitization, and insecure default configurations. Since Bolt.new prioritizes rapid prototyping, security concerns like XSS prevention and CSRF protection are frequently overlooked in the generated output. UNPWNED scans Bolt.new applications for these vulnerabilities and provides specific remediation steps.

Question 2

Is Bolt.new safe for production?

Accepted Answer

Bolt.new is designed for rapid prototyping and can generate working applications, but the output typically requires security review before production deployment. The AI generates code that works functionally but may skip important security patterns like proper session management, secure cookie configuration, and error handling that prevents information leakage. Database queries generated by Bolt.new may also lack parameterization, creating SQL injection risks. Run an UNPWNED security scan on your Bolt.new project before deploying to production to catch these issues.

Question 3

Does Bolt.new expose secrets in code?

Accepted Answer

Bolt.new can inadvertently place API keys, database credentials, and other secrets directly in client-side JavaScript files. When secrets are embedded in frontend code, they become visible to anyone inspecting the page source or network requests. This is especially dangerous with database connection strings and third-party API keys that grant write access. Always review the generated code for hardcoded credentials and move them to environment variables. UNPWNED scans for exposed secrets, API keys, and credentials in your deployed application.

Question 4

How to secure a Bolt.new app?

Accepted Answer

Begin by auditing all API routes for proper authentication and authorization checks. Move any hardcoded secrets to environment variables and ensure they are not exposed in client-side bundles. Add input validation and sanitization on both client and server, and implement Content-Security-Policy headers to mitigate XSS attacks. Configure CORS to only allow requests from your own domain rather than accepting all origins. UNPWNED provides a comprehensive scan covering secrets exposure, header configuration, CORS policy, and API security for Bolt.new applications.

Question 5

Does Bolt.new validate user input?

Accepted Answer

Bolt.new-generated code typically includes minimal client-side validation for form fields but often lacks server-side validation entirely. Client-side validation alone is insufficient because attackers can bypass it by sending requests directly to your API endpoints. Without server-side validation, your application is vulnerable to SQL injection, XSS, and other injection attacks through malformed input. Always add server-side validation using libraries like Zod or Joi for any Bolt.new-generated API routes. UNPWNED checks for common injection vulnerabilities and missing input validation in your application.

Question 6

Are Bolt.new API routes authenticated?

Accepted Answer

Bolt.new often generates API routes without authentication middleware, leaving endpoints accessible to anyone who discovers them. This means sensitive operations like data creation, modification, and deletion can be performed by unauthenticated users. Even when authentication is present, authorization checks that verify whether the authenticated user should have access to specific resources are frequently missing. This can lead to Insecure Direct Object Reference (IDOR) vulnerabilities. UNPWNED scans your API routes to detect missing authentication and authorization controls.

Question 7

Does Bolt.new add CORS protection?

Accepted Answer

Bolt.new frequently generates API routes with overly permissive CORS configurations, often setting Access-Control-Allow-Origin to wildcard (*). This allows any website to make requests to your API, which can be exploited for data theft if combined with authentication tokens stored in cookies. Proper CORS configuration should whitelist only your own domain and explicitly specify allowed methods and headers. Misconfigured CORS is one of the top issues found in AI-generated web applications. UNPWNED tests your CORS configuration and reports overly permissive settings.

Question 8

How to check if my Bolt.new app is vulnerable?

Accepted Answer

Deploy your Bolt.new application to a staging environment and run a security scan to identify vulnerabilities before going live. Key things to check include exposed secrets in your JavaScript bundle, missing authentication on API routes, and absence of security headers. Review your CORS configuration to ensure it is not set to wildcard, and verify that database queries use parameterized statements. UNPWNED performs automated checks across more than 30 security categories specifically relevant to AI-generated applications like those built with Bolt.new.

Question 9

Can Bolt.new apps be used for sensitive data?

Accepted Answer

Using Bolt.new for applications that handle sensitive data like personal information, financial records, or health data requires significant additional security work beyond what the AI generates. The generated code typically lacks encryption at rest, proper access controls, and audit logging that regulations like GDPR and HIPAA require. Without these safeguards, a data breach could result in legal liability and regulatory fines. If you must handle sensitive data, treat the Bolt.new output as a starting point and add comprehensive security layers. UNPWNED can help identify the specific security gaps in your application before you store any sensitive information.

Question 10

What security headers does Bolt.new set?

Accepted Answer

Bolt.new typically does not configure security headers in the generated application code. Headers like Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and Permissions-Policy are usually absent. These headers are essential for preventing cross-site scripting, clickjacking, MIME sniffing, and other browser-based attacks. The deployment platform may add some basic headers, but a comprehensive security header configuration must be added manually. UNPWNED checks for all recommended security headers and grades your application based on the Mozilla Observatory scoring standard.
