What Lovable's scan covers
When you publish, Lovable runs a quick scan. It looks for tables without row-level security, database settings such as leaked-password protection being off, known vulnerabilities in npm packages and an MCP server exposed without sign-in. A separate deep scan, which you start yourself, reviews the code for problems such as missing access checks, injection, leaked secrets and payment flaws.
Run both. Lovable's own documentation says the tools cannot guarantee complete security and recommends a professional review for apps that handle sensitive data. A scanner can tell that a policy exists. It cannot tell that your sales staff should see only their own clients.
Who can read your data
Most serious problems in Lovable apps are data access problems. The browser talks to the database directly, so row-level security policies are what keep one customer's records away from another's. In 2025 a researcher found about 170 of 1,645 apps from Lovable's showcase with tables open this way (CVE-2025-48757).
Check that every table holding user or business data has RLS on, that each policy limits rows to their owner or team, and that views and database functions do not get around it. Our guide to Supabase RLS for Lovable apps walks through each check and a test with two accounts.
Secrets and API keys
Open your published app, view the page source and search the loaded JavaScript for words like secret, sk_ and service_role. Anything you find there is public. Stripe secret keys, OpenAI or Anthropic keys, email provider keys and Supabase's secret key belong in edge functions or another server, stored as secrets in the project settings.
If a secret was ever in the frontend or in a public GitHub repository, rotate it in the provider's dashboard. Deleting the line does not remove it from the history or from copies people already have.
Sign-in and roles
Check that confirmation, password reset and sign-in links point to your real domain, not the preview. Leaked-password protection, which the scan checks, rejects passwords that appear in known breaches; turn it on if your Supabase plan includes it.
If the app has admins or staff, every admin action needs a check in the database or a server function. Hiding a button only hides it: the request behind it still works for anyone who sends it.
Payments and webhooks
Access should change only when the payment provider's webhook says so, and each webhook's signature should be verified. Check that a webhook delivered twice does not grant access twice, and that a refund or failed renewal removes what it should.
Inputs, uploads and AI features
Validate what users submit on the server as well as in the form: length, type and whether this user may submit it at all. Keep uploaded files in a private storage bucket unless they are meant to be public.
If the app sends user text to an AI model, limit how often each user can call it, keep the model's API key on the server, and do not let the model's output run queries or actions without checks of their own.
Dependencies, backups and errors
Update the packages the scan flags, starting with the ones the browser loads. Turn on database backups and try a restore once. Add error tracking so a failure on a sign-in or payment path reaches you before a customer reports it.
When to get a second pair of eyes
If the app stores personal data, takes payments or has several user roles, a review by someone who did not build it is worth doing before launch. It should cover data access, secrets, sign-in, payments, backups and deployment, use only the access you give, and end with a ranked list of what must be fixed first. No review can promise an app is fully secure; a good one tells you exactly what it checked.
Frequently asked questions
Is Lovable secure?
The platform is a reasonable foundation and scans projects before publishing. The security of your app depends on its database policies, where its keys live and how roles are checked, which you or a reviewer still need to verify.
Is vibe coding safe for production apps?
It can be, if the generated code goes through the same checks as any other code: access rules, secrets, input validation, payments and monitoring. The risk is shipping what works in the preview without anyone reviewing those parts.
Is Lovable's security scan enough?
It catches common misconfigurations and known vulnerable packages. It cannot check your business rules, so test what each type of user can see and change, and get a review if the app handles sensitive data or payments.
How much does a security review of a Lovable app cost?
Our launch check costs $1,500 and takes three business days. You get a written report with each issue ranked by risk and a fixed price for the fixes, and the fee is credited against fixes ordered within 30 days.
Not sure your app is ready for real users?
Our launch check reviews sign-in, data access rules, secrets, payments, backups and deployment, using only the access you give us. In 3 business days you get a written report with each issue ranked by risk and a fixed price for the fixes. $1,500, credited against fixes ordered within 30 days.
If you already know what needs fixing, book a call and get a fixed quote for the fix instead.
