Lovable Security Checklist: Before You Launch

A useful Lovable security checklist starts with three questions: what did the platform flag, who can access your data, and what does your published app expose? Answer all three before treating a working preview as a launch-ready product.

This guide is for builders moving from a prototype to an app with real users. The examples are hypothetical; they describe tests to run on your own project, not findings from a VibeShield investigation.

Start with Lovable’s own security findings

Lovable documents Quick and Deep security scans. Its Quick scan covers defined database, dependency and MCP checks, while the Deep scan reviews application code and permissions more broadly. Review the available findings before publishing, then confirm which checks ran for your project. Lovable’s security overview explains the current scope and controls.

For each finding, record the affected component, evidence and intended behavior. Ask your builder to explain the proposed change before applying it. A generated fix deserves the same review as any other change to authentication or data access.

Keep a short launch record: the version reviewed, unresolved findings, accepted exceptions and the person responsible for each follow-up. This prevents a warning from disappearing into an old chat conversation.

Write down the data access rules

Imagine a project-management app with private notes and a public project directory. The directory can be visible to visitors; private notes should be available only to authorized members. Document that difference for every collection of data.

Use two test users and an anonymous browser session with synthetic records. Check whether user A can view or change user B’s private note, whether a logged-out visitor sees private data, and whether a removed member retains access. Verify the server or database decision rather than relying on a hidden button.

If your project uses Supabase, review its access rules and follow the Supabase RLS testing guide. Row Level Security, or RLS, applies rules to individual database rows; merely enabling it does not establish that your rules match your app.

Follow a secret from storage to execution

Choose one integration, such as an email provider. Identify where its private credential is stored, which server function uses it, and which browser request triggers that function. Check that the request cannot be used to send arbitrary mail or act for another user.

Lovable recommends secret storage and server-side calls for private API credentials. Use that boundary rather than placing a secret in a React component. Its API-key guidance explains the platform approach.

Do not paste real credentials into a review prompt or an issue description. If a private key has already been public, remove the exposure and rotate or revoke it with the provider; deleting the visible text does not invalidate copied credentials.

Review the published URL

Test the actual deployment in a fresh session. Confirm that expected pages load, login redirects work, sign-out ends access, and private responses are not returned to anonymous users. Also review public files, browser JavaScript and security response headers.

Record a distinction between an issue, an intended public resource and a check that could not run. A blocked scanner request gives you a coverage gap, not proof that the underlying app is secure.

The Lovable security scanner page explains VibeShield’s complementary public-URL checks. Its anonymous scan is a limited passive security pass; deeper account scans require domain verification. Neither path replaces testing your authenticated workflows.

Ask for a focused fix

Try this prompt with synthetic examples:

Review the private-note access flow. State the intended permissions for visitors, owners and members. Identify where those permissions are enforced. Propose the smallest change and tests proving that a non-member cannot read or modify a note. Do not broaden access to make the test pass.

Review the diff, test legitimate access as well as denied access, publish, and repeat the relevant live check. Use the AI app security checklist to track the remaining launch work.

Common questions

Does a clean platform scan replace a manual review?

No. It reports on its checks and scope. Your app’s membership rules, billing decisions and sensitive workflows still need explicit tests.

Should I review security only before the first launch?

Repeat the affected tests after changes to authentication, data structures, integrations or permissions. Keep the launch checklist attached to the current deployed version.
