Vibe Coding Security Checklist: Is Your App Ready for Real Users?

Start with the app's real risks

Write down what the app stores and what users can do: private documents, customer records, paid subscriptions, staff approvals, or public content. Identify which mistakes would expose information, lose money, or stop the business. Those flows deserve the most attention. A small public directory and a portal holding private files need different levels of review.

For every check below, record the result, who verified it, and any work still open. Run tests only against apps you own or are authorized to assess, using staging and test accounts. This is a launch review, not a substitute for a security assessment tailored to sensitive or regulated data.

1. Verify permissions beyond the screen

Sign-in establishes identity. Authorization decides what that person can read or change. A hidden admin button does not protect the operation behind it. OWASP recommends checking permissions on every request, including requests that bypass the interface.

• Create test users in two separate accounts or organizations. Confirm one cannot view, edit, export, or delete the other's private records.
• Check direct file links and API requests, not just the pages that show them. Test signed-out access and access after a session expires.
• Test a normal user against administrative operations. Verify invitations and role changes cannot grant more access than intended.

Evidence to keep: an access matrix showing each role, allowed actions, and tests of denied actions. If your app uses database row policies, include those policies and the server operations that can bypass them in the review.

2. Separate public configuration from private credentials

Ask an engineer to review browser code, repository history, network responses, and logs for private credentials. Payment secret keys, privileged database credentials, and private API tokens must stay out of browser code. Some public client identifiers are intended to be visible; the review must distinguish them from secrets rather than flag every key-shaped string.

If a secret has been exposed, removing it from the current source is not enough. Rotate or revoke it, update the server configuration, and assess where it was used. Evidence to keep: a list of credential owners and storage locations, without copying the secret values into the report.

3. Test payments and important state changes

A checkout success screen should not be the authority for a paid account. Check that trusted server logic verifies payment events before granting access. Test unsuccessful payment, cancellation, delayed delivery, and duplicate events. A retried event should not charge again or repeat a one-time action.

The same reasoning applies to approvals, credits, orders, and account deletion. Ask what happens if the browser closes between steps or an external service times out. Evidence to keep: a test record connecting an event to the correct final state, including failed and retried events.

4. Check inputs, uploads, and abuse limits

Validation in a form helps the user; the server still needs to enforce the rules. Review file type and size limits, where uploads are stored, and who may download them. Check that expensive actions have appropriate limits: email sending, AI calls, searches, exports, and file processing can create unexpected costs.

Use practical tests tied to your product. Can a user submit an invalid price, request an export from another organization, or trigger the same paid action repeatedly? Evidence to keep: the server-side rules and tests that show invalid requests are rejected.

5. Prove you can restore data and roll back a release

Having a backup setting is different from recovering the application. Confirm what is backed up, how long copies remain available, and who can restore them. Rehearse restoration in a separate environment with test data. Include uploaded files and configuration where the app depends on them.

Before a release, identify how to return to the previous version. Database changes can make code rollback harder, so the plan needs to cover both. Evidence to keep: the recovery steps, a successful rehearsal, and an agreed tolerance for lost data and downtime.

6. Assign responsibility after launch

Choose who receives error alerts, checks dependencies, handles access changes, and approves releases. Keep customer data and credentials out of logs while retaining enough context to investigate failures. Monitoring should focus on the journeys users rely on, such as sign-in and purchase completion.

A scanner can help find known issues, but it cannot prove every business rule is correct. Review permissions and important flows again when features change. If you are using Lovable, our Lovable production-readiness guide explains how these checks relate to its security and hosting options.

Make a launch decision from the results

An unresolved cross-account data leak, exposed private credential, or incorrect payment entitlement is a reason to pause the affected release. A cosmetic issue can usually be prioritized separately. Record the blockers, the person fixing them, and how the fix will be verified. Avoid a single score that lets several minor passes hide a critical failure.

If you need help interpreting the results, our app cleanup and production support service can scope the review and fixes. For budgeting, read what drives the cost of finishing and maintaining a vibe-coded app.
