HOW TO SECURE FIGMA MAKE - SECURITY GUIDE | VIBEEVAL

Figma Make Security Context

Figma Make turns a Figma frame into a working React app — generated quickly, polished visually, light on backend logic. The security gap lives at the boundary: the design has a “Sign Up” button, the generated app has a form that posts somewhere, and “somewhere” needs auth, validation, rate limits, and storage that you have to add yourself. Treat the Figma Make output as a frontend draft; the backend is on you.

Security Checklist

1. Add server-side validation on every form

The Figma Make output validates client-side at most. Every endpoint behind a form needs a server-side schema check:

import { z } from "zod"
const Schema = z.object({ email: z.string().email(), name: z.string().min(1).max(100) })
const data = Schema.parse(await req.json())

Without this, the endpoint accepts any payload — including unexpected fields that may map to sensitive columns (mass assignment).

2. Sanitize dynamic content before rendering

Search for dangerouslySetInnerHTML in the generated React. Every match needs DOMPurify if the content is user-controlled. The bug ships when a “blog post” component renders the post body as HTML.

3. Implement authentication

Figma Make designs the auth screens; the actual auth is a stub. Pick a provider (Clerk, Auth.js, Supabase Auth) and wire it in before connecting any data screens. The “logged in” state in the generator is local state — it survives a refresh, looks real, and doesn’t authenticate anything.

4. Audit data binding for sensitive fields

The visual data-binding panel can connect a UI element to any field of the source object — including ones you didn’t mean to expose. If a profile card binds to the user object, check that the source object is filtered server-side to the user-safe fields, not the full DB row.

5. Protect application state from tampering

If your generated app stores isAdmin or role in client state, that state is editable in DevTools. Authoritative role checks must happen server-side on every request, not client-side once at login.

6. Secure API calls

Add Authorization: Bearer ${token} to every fetch — but ensure the token is read from an httpOnly cookie or a secure session, not from localStorage. Confirm every URL is HTTPS; the generator sometimes emits http://localhost references that survive into production.

7. Add authorization checks on every protected endpoint

The frontend hiding a button does not protect the endpoint. For each API route, the first thing the handler does is check the session and check that this session can access this resource (BOLA / IDOR). See BOLA in AI-generated CRUD.

8. Configure CORS to your production origin

Default API templates ship Access-Control-Allow-Origin: *. With cookies, this is a credential-stuffing pivot. Pin to your actual frontend origin. See CORS credentials misconfig.

9. Implement rate limiting on auth and form endpoints

Use express-rate-limit (Node) or the framework equivalent: 10 requests per IP per minute on /login, /signup, /reset-password. Without this, the contact form is a free email-spam relay and the login is a free credential-stuffing target.

10. Add CSRF protection for cookie-authed endpoints

If you use cookie auth (not Bearer tokens), enable CSRF tokens on every state-changing request. Frameworks like Next.js (with the csrf middleware) and Remix have built-in helpers. Token-authed APIs (Bearer in Authorization header) don’t need CSRF for non-credentialed origins.

11. Audit third-party scripts

Any <script src="https://..."> from a domain you don’t control runs with full access to your DOM. Self-host or add Subresource Integrity (integrity="sha384-...").

12. Set security headers

In your hosting config (Vercel vercel.json, Netlify _headers, etc.):

Content-Security-Policy: default-src 'self'
X-Frame-Options: DENY
X-Content-Type-Options: nosniff
Strict-Transport-Security: max-age=31536000; includeSubDomains

Verify with the Security Headers Checker.

13. Clear sensitive state on logout

Generated logout handlers often setUser(null) without clearing tokens, draft form data, or cached responses. Make sure the logout flow clears every storage location (cookies, localStorage, in-memory caches) and forces a redirect.

14. Review export-time secrets

If Figma Make exported your prototype with API keys for connected data sources, those keys are in the exported repo. Search the export for apiKey, secret, token and rotate / move every match before pushing to a public repo.

15. Run a full security scan
