Vibe Code Security Audit for AI-Built Apps

Your prototype works. Now check whether its data, permissions and secrets are protected. I review AI-assisted apps built with tools such as Cursor, Lovable, Bolt, Replit and v0, and turn findings into a prioritised plan your team can act on.

  • Secrets & Configuration
  • Auth, Roles & Tenant Access
  • Database Rules & API Security

Choose the review your app needs now

Start with a focused exposure review or a deeper assessment of your code and configuration. Remediation can follow as a separate, agreed milestone.

Exposure review

Check what the browser can see

For a recently launched app that needs an initial exposure review.

  • Review agreed public pages, client bundles and configuration exposure
  • Check which API credentials belong on the server
  • Review accessible data paths within the authorised scope
  • Receive documented findings and recommended next steps

A focused first pass, not a replacement for a deeper code and configuration review.

Code & configuration

Review the boundaries that protect your app

For products handling accounts, payments or sensitive information.

  • Review agreed code, database rules and hosting configuration
  • Check roles, record ownership and tenant separation
  • Trace API, upload and integration risks to their cause
  • Receive severity-ranked findings with evidence and remediation guidance

Depth depends on the codebase, roles, integrations and environments agreed in scope.

Remediation & retest

Turn findings into verified changes

For teams that want implementation help after the review.

  • Agree which findings I will fix and which your team owns
  • Plan secret rotation, access-control changes and safer configuration
  • Add focused regression checks where appropriate
  • Retest agreed fixes and document remaining risks

Implementation and retesting are explicitly scoped, not silently bundled into every audit.

Send a short description of your app, its stack and your main concerns. I will propose a scope, timeline and custom quote.

A working screen is not proof of protected data

AI coding tools can help you ship a useful flow quickly. The important questions sit behind that flow: does the server verify ownership, can one tenant access another tenant's records, and do database rules match what the interface appears to allow?

A vibe code security audit connects those questions to the implementation. I review the agreed parts of the app, gather evidence for identified issues and explain their impact in plain language. You get actionable next steps rather than a list of unexplained scanner warnings.

The review follows your stack: Supabase row-level security and storage policies, Firebase rules, Next.js server-side operations, Laravel policies or other backend access controls. Public configuration is distinguished from private credentials; the presence of a publishable key alone is not treated as a vulnerability. The goal is to understand the permissions and data paths behind it.

A developer's view of the problem and the fix

I'm Usman Nadeem, a freelance full-stack and AI engineer based in Lahore, Pakistan. My 12+ years of development experience span 500+ projects and 150+ clients, with 95% repeat or referral. I bring that product-building context to understanding how your frontend, backend and integrations fit together.

You work directly with the person reviewing the implementation. Findings explain the affected component, likely impact, supporting evidence and recommended action. If you need help applying the changes, we agree a remediation milestone so responsibility and cost stay clear.

Before the next launch, check the boundaries that matter.

Tell me what the app does, which tools and services it uses, and whether you need review only or help with fixes. No passwords or secret keys are needed in your initial enquiry.

1.Scope and authorise
We agree the application, environments, code areas, user roles and permitted checks. You confirm ownership or authorisation. We define exclusions, safe test conditions, access requirements and how findings will be communicated before review begins.
2.Review and validate
I examine the agreed code, configuration and relevant application behaviour, using test accounts and non-production data where practicable. Checks are selected for the architecture and scope, not applied as a blanket promise of complete coverage.
3.Prioritise and explain
You receive documented findings with severity, affected components, evidence, impact and recommended remediation. Important findings are communicated through the agreed channel and handling process, with sensitive details kept out of public reports.
4.Remediate and retest
Your team can implement the recommendations, or I can quote the agreed fixes separately. Retesting checks those changes within the agreed scope and records their status, remaining risks and any follow-up work.

What the review can cover

The checklist is adapted to your architecture, data and agreed scope, with attention to the boundaries most likely to affect real users.

Secrets, identity and data access

  • Private credentials in browser code, public configuration, repositories or logs
  • Authentication, session handling and server-side authorisation
  • Record ownership, admin permissions and separation between tenants
  • Supabase row-level security, Firebase rules and storage permissions
  • File access and upload controls, including private objects and signed links

APIs, integrations and configuration

  • Input validation and unsafe handling of user-supplied content
  • API routes and server operations that rely only on UI restrictions
  • Webhook verification and payment-event handling where relevant
  • Rate limits and controls around operations that incur usage costs
  • Dependency advisories, cookie settings, CORS and deployment configuration

For AI-powered features, the scope can also include tool permissions, retrieval access boundaries and handling of untrusted content. New functionality belongs in a separate AI development engagement.

A report that leads to a better next decision

Know what was reviewed, what needs attention and how to move from findings to an agreed fix plan.

Evidence you can act on

Each documented finding identifies the affected area, supporting evidence and potential impact, with enough context for your team to understand the problem.

A prioritised remediation plan

Severity and practical next steps help you address urgent risks first, then plan the remaining work around your product and dependencies.

Clear ownership of the fixes

Decide which changes your team will make and which need implementation support. Larger refactors or rebuilds are estimated separately.

A useful handoff

Agreed retest results and follow-up notes help you carry the work forward, alongside sensible development rules for future AI-assisted changes.

Vibe code security audit FAQ

What is a vibe code security audit?

It is a scoped security review of an AI-assisted application, focusing on its code, configuration and relevant behaviour. Typical areas include exposed private credentials, authentication, permissions, database rules and API boundaries. You receive prioritised findings and remediation guidance.

Which AI coding tools and stacks can you review?

I review applications built with tools such as Cursor, Claude Code, Lovable, Bolt, Replit and v0. The checks follow the resulting stack, including React, Next.js, Laravel, Supabase or Firebase where applicable, rather than assuming every generated app has the same issues.

Is a public Supabase or Stripe key always a leak?

No. Some publishable keys are designed for client-side use. The review distinguishes those from private credentials and examines the permissions behind them. Database policies and server-side authorisation still matter. Privileged Supabase service-role credentials belong in trusted server-side code.

Can you check access between users or tenants?

Yes, when included in scope. I review server-side ownership checks, role permissions and tenant boundaries, using agreed test accounts and records. Hiding a button or route in the interface is not a substitute for checking access on the server.

Do you need access to my source code?

A focused exposure review may start with agreed public application behaviour. A deeper review usually needs relevant code and configuration access, plus suitable test accounts. Access is arranged privately after scope and authorisation are agreed; do not paste secrets into the enquiry form.

Do you fix the findings too?

Remediation can be quoted separately. An audit report provides findings and recommended actions; implementation support covers the specific fixes we agree. Retesting is also defined in scope so the status of those changes is clear.

Is this a penetration test or compliance certification?

The standard offer is a scoped code and configuration security review, with agreed application checks. Formal penetration testing, certification and compliance assessments are not included by default. Any additional testing requirements must be discussed before the engagement.

Does an audit guarantee my app is secure?

No review can establish that an app has no vulnerabilities. Findings reflect the agreed scope, access and application version reviewed. The report helps you reduce identified risks and plan further work; future changes and dependencies still need attention.

How long does the audit take and what does it cost?

Both depend on the size of the application, roles, integrations, environments and review depth. After scoping, I provide a custom quote and proposed timeline. Communication and handling of important findings are agreed for the engagement; there are no fixed prices on this page.

How do we get started?

Send a short description of your app, stack and main concerns through the contact form. Include the product URL if appropriate, but no passwords, private keys or customer data. We confirm authorisation, scope and secure access arrangements before review work starts.
