Security for apps created with Lovable and AI: secrets, roles, RLS and JWT

How to audit an AI-generated app: authentication, permissions, RLS, JWT, API keys, CORS, uploads, and per-user tests.

Security for apps created with Lovable and AI: secrets, roles, RLS and JWT

A pretty login does not equal security

An application can ask for a password and still expose another client's resources because the server does not check who owns each record. The login screen only solves part of authentication. Authorization decides what operation each user can perform. They are two different problems.

What to check before opening an app to the public

Check who creates tokens, how they expire, and which endpoints verify permissions. If you use a database with Row Level Security, validate that the policies actually represent the business roles. Do not trust a JSON field sent by the browser that says isAdmin: true. PostgreSQL, Stripe, SMTP, and API secrets go on the server side; not in a React bundle or in exposed VITE_ variables.

Example: two companies and the same panel

The SaaS has company A and B. In the interface, administrator A sees only their clients. Test, in an authorized way on staging, a normal request with an identifier belonging to B: the backend must return 403 or 404 without leaking information. Then check that a read-only account cannot create or delete records. Automate those tests. Hiding buttons is not enough.

The five most urgent reviews

1. Authentication and authorization verified on every critical route. 2. Data isolation between companies or users. 3. Secrets and credentials outside the frontend and Git. 4. Validation and limits on file uploads and requests. 5. Incident logging, library updates, and response plan.

Difference between a scanner and an audit

A scanner finds known patterns. It may fail to understand business rules, for example who has the right to view a specific invoice. Role-based testing and backend route analysis are essential when there is sensitive data.

Frequently asked questions

### Does JWT protect my API by itself? No: the server must validate the token and check permissions on each resource. ### Does RLS eliminate all permission issues? No. It is an important layer but policies and routes must be configured correctly. ### Is it safe to hide the admin button? It only improves the interface. The endpoint must check authorization. ### What do I do if I published a private key? Revoke or rotate it immediately and review usage and cost logs.

What about ArduMaker?

This work fits the idea of a service that reviews AI-generated code, implements what is necessary, and takes it to operable infrastructure. The future page ardumaker.com/lovable will present this migration and deployment modality. The page does not exist yet, so it should not be announced as an automatic service already available. For the products that exist today you can visit ardumaker.com. The real scope is determined with an audit: permissions, data, integrations, and maintenance.

Editorial review: October 2026. Official references prevail over generic examples; make a backup and staging tests before any intervention in production.
