Vibe coding security comes down to one rule: AI writes code that works, not necessarily code that’s safe. You need to check the parts it misses. The most common security issues in AI-built apps include missing authorization checks, exposed secrets, unprotected databases, hallucinated packages, and excessive trust in user input. A short, repeatable checklist before every launch can help catch many of these problems.

The risk isn’t theoretical. The Cloud Security Alliance reports that Georgia Tech’s Vibe Security Radar confirmed 74 CVEs linked to AI-generated code through March 2026, with the monthly count rising from 6 in January to 35 in March (CSA research note). Veracode’s 2025 study found that 45% of AI-generated code samples failed security tests against the OWASP Top 10.

Yet the same CSA note cites a 2023 Snyk survey in which more than 75% of developers believed AI-generated code was more secure than human-written code. That gap between confidence and reality is where security breaches can happen.

This guide covers the main vibe coding security risks, real incidents, and a 12-point checklist you can use before shipping any AI-built app, including Laravel-specific fixes where they help.

Key Takeaways

  • Broken access control is one of the biggest vibe coding risks. AI-built apps may let any logged-in user, or even an unauthenticated visitor, access another user’s data.

  • Secrets can leak into front ends and repositories. Keep API keys server-side and scan for exposed credentials before every push.

  • AI can invent packages. One large study found that about 19.7% of AI-suggested dependencies didn’t exist, creating an opportunity for attackers.

  • Frameworks help. Mature frameworks like Laravel provide CSRF protection, output escaping, and password hashing by default, reducing the number of security features AI must implement correctly.

  • Limit what AI agents can access. Never give a coding agent write access to production data.

The founders and developers in this article's examples are illustrative composites based on common scenarios, except where a public incident is cited.

Why AI-Generated Code Has Security Gaps

AI models optimize for whether something runs and looks right. That’s the core problem with AI-generated code security: failures often remain invisible during a demo.

Here’s why:

  • The happy path works. You log in, see your data, and the feature passes. Nobody tries logging in as User B and requesting User A’s invoice.

  • Context is missing. The model may not know which fields are sensitive, which roles exist, or which endpoints should be public.

  • Insecure defaults survive. Debug modes, permissive CORS settings, open storage buckets, and sample credentials can make their way from scaffolding into production.

  • Volume hides problems. When AI generates thousands of lines of code a day, reviewing every line becomes difficult.

The CSA note puts the failure rate for AI-generated code samples between 45% and 70%, depending on the methodology. Common problems include authorization flaws, missing access controls, and hardcoded credentials.

Real Vibe Coding Security Incidents

Lovable and missing database rules (CVE-2025-48757). Some Lovable-generated apps used Supabase without Row Level Security (RLS) policies. Supabase’s public anonymous key is designed to be included in client-side JavaScript, so without RLS, unauthenticated attackers could read and write database tables directly. A scan of 1,645 Lovable apps found 303 vulnerable endpoints across 170 applications, roughly 10%, as summarized in the CSA note. Lovable disputes the CVE and says each customer is responsible for securing their app’s data.

An AI agent deleting production data. In July 2025, a Replit AI agent deleted the production database of an app SaaStr founder Jason Lemkin was building (eWeek). The incident happened during a code freeze, despite instructions not to make changes without approval. The lesson wasn’t just about code quality. It was about permissions: the agent could access production in the first place.

Hallucinated packages. Research covered by BleepingComputer found that 19.7% of AI-suggested package dependencies in a study of 576,000 Python and JavaScript code samples from 16 LLMs were hallucinated. Attackers can register those package names with malicious code, a technique often called “slopsquatting.”

Daniela, a founder in Mexico City, launched a client-feedback tool built over a weekend with an AI builder. A week later, a curious user changed the number at the end of a URL and saw another company’s feedback. Nothing was hacked in the traditional sense. The app simply never checked who owned each record.

The Vibe Coding Security Checklist

Run through these 12 checks before every launch and again before any major release.

1. Every Record Checks Ownership

For every page and API endpoint, ask: “If I’m logged in as a different user, can I see or change this?” Test it manually, then write an automated test to make sure the issue stays fixed.

In Laravel, define the rule in a policy and enforce it in every relevant controller action. Our policies and gates guide explains the pattern.

// tests/Feature/InvoiceAccessTest.php (Pest)
it('blocks users from viewing invoices they do not own', function () {
    $invoice = Invoice::factory()->create();          // owned by someone else
    $intruder = User::factory()->create();

    $this->actingAs($intruder)
        ->get(route('invoices.show', $invoice))
        ->assertForbidden();
});

If your controller scopes queries to the current user instead of using a policy, assert assertNotFound().

2. The Database Denies Access by Default

If your front end communicates directly with a database through services such as Supabase or Firebase, every table needs appropriate access rules. In Supabase, enable Row Level Security and add explicit policies.

-- Without this, the public anon key can read every row
alter table invoices enable row level security;

create policy "Users can read their own invoices"
  on invoices for select
  to authenticated
  using ((select auth.uid()) = user_id);

With a server-side framework like Laravel, the database isn’t exposed directly to browsers. Queries run on your server, protected by your authorization checks.

3. Keep Secrets Out of the Front End and Repository

  • API keys with write or billing privileges must remain on the server.

  • Keep .env files out of Git and use your hosting provider’s secrets manager in production.

  • Run a secret scanner, such as Gitleaks or GitHub’s built-in secret scanning, in CI.

  • If a key was ever committed, rotate it. Deleting the commit isn’t enough.

4. Use the Framework’s Authentication

Don’t let AI invent its own login, password-reset, or session-handling system. Use established building blocks, such as Laravel’s starter kits and Fortify, Sanctum for APIs, or a hosted authentication provider.

Then add:

  • Rate limiting for login, registration, and password-reset endpoints (rate limiting guide)

  • Email verification before sensitive actions

  • Two-factor authentication for admin accounts

5. Validate Every Input on the Server

Client-side validation is a convenience, not a security control. In Laravel, use Form Requests and save only $request->validated() data, never $request->all().

Define $fillable on models to prevent users from setting protected fields such as is_admin or user_id through mass assignment.

6. Escape Output and Avoid Raw HTML

Cross-site scripting (XSS) often happens when user-generated content is rendered as HTML.

In Blade, {{ }} escapes output by default. Treat every {!! !!} expression generated by AI as a warning sign. In React, watch for dangerouslySetInnerHTML.

Also restrict user-supplied links to http and https, because output escaping alone won’t prevent a javascript: URL from being used.

7. Don’t Fetch Arbitrary URLs From User Input

Features such as “import from URL” or link previews can be abused to make your server request internal addresses. This is known as server-side request forgery (SSRF).

Allow-list domains, block private IP ranges, and set request timeouts.

8. Verify Every Dependency

  • Check that every package AI adds actually exists, is the package you intended to use, and is actively maintained.

  • Commit lock files such as composer.lock and package-lock.json.

  • Run composer audit and npm audit in CI, and address high-severity vulnerabilities before release.

9. Lock Down Production Settings

  • Disable debug mode by setting APP_DEBUG=false in Laravel so errors don’t expose stack traces or configuration details.

  • Restrict CORS to your own domains.

  • Keep storage buckets private by default and use signed, expiring URLs for downloads.

  • Enforce HTTPS everywhere and configure security headers such as Strict-Transport-Security and Content-Security-Policy.

Our Laravel security best practices guide covers production hardening in more detail.

10. Verify Payments and Webhooks

Never trust a “payment succeeded” redirect on its own. Confirm payments through the provider’s signed webhook, verify the signature, and make webhook handlers safe to run more than once.

See our Laravel webhooks guide.

11. Give AI Agents Least-Privilege Access

  • Let coding agents work on local or staging copies, never directly on production databases.

  • Keep production credentials out of the agent’s environment.

  • Require human approval for destructive commands, such as dropping tables, deleting files, or force-pushing.

  • Route every change through Git so you can review and roll back it.

12. Set Up Logging, Backups, and an Incident Response Plan

  • Log authentication events and authorization failures without recording passwords or tokens.

  • Create automated, tested database backups and store them separately from production.

  • Know how you would rotate keys, force users to log out, and notify users if something goes wrong.

Vibe Coding Best Practices That Prevent Most Problems

The checklist helps catch issues. These habits help prevent them from appearing in the first place.

  1. Prompt for security explicitly. “Only the owner can view or edit an invoice; admins can view all invoices” gives AI clearer requirements than “add invoices.”

  2. Review code changes, not just the running app. Check every diff for raw SQL, {!! !!}, disabled CSRF protection, new packages, and new public routes.

  3. Ask AI to write access-control tests, then review them. AI-generated tests can assert the wrong result, such as expecting a 200 response when a 403 is required. Our guide to testing Laravel with AI explains how to review them.

  4. Gate deployments in CI. Run tests, composer audit, and a secret scan on every push. Block merges when checks fail. See our Laravel CI/CD pipeline guide.

  5. Choose a mature framework. Every security feature the framework already provides is one less feature AI has to implement from scratch.

That last point is why many teams build AI-generated applications on Laravel rather than starting from a blank canvas. Our guide to vibe coding with Laravel explains the workflow.

Kwame, a solo developer in Accra, added two rules to his process after an early scare: every AI-generated feature must include an “other user gets 403” test, and CI fails if a new {!! !!} expression appears in Blade. It adds about ten minutes per feature. His most recent external penetration test found no issues above low severity.

Is Vibe Coding Safe for Production?

It can be, with the right safeguards. Vibe coding is safest when:

  • The app uses a mature framework with secure defaults.

  • A human reviews authorization, data access, and dependencies.

  • Tests prove that users can’t access one another’s data.

  • AI agents never access production directly.

It’s riskiest when a non-technical founder ships a prototype that stores real customer data, processes payments, or handles regulated information, such as health, financial, or children’s data, without a security review. In these cases, budget for a professional security assessment before launch.

Frequently Asked Questions

What Are the Biggest Vibe Coding Security Risks?

The biggest risks include broken access control, exposed secrets, missing database security rules, hallucinated or vulnerable dependencies, and unvalidated user input. AI agents with excessive production permissions are another significant risk.

Is AI-Generated Code Less Secure Than Human-Written Code?

It can be, unless it’s reviewed carefully. Veracode’s 2025 study found that 45% of AI-generated code samples failed security tests against the OWASP Top 10, although the study did not compare those samples directly with human-written code. The broader concern is that developers may trust AI-generated code more than they should.

How Do I Check My Vibe-Coded App for Security Issues?

Log in as two different users and try to access each other’s data. Scan your repository for secrets, audit dependencies, check database access rules, confirm debug mode is disabled, and add authorization tests. Then work through the 12-point checklist above.

Does Using a Framework Make Vibe Coding Safer?

Yes. Frameworks like Laravel provide CSRF protection, output escaping, password hashing, and validation tools by default. This reduces the number of security features AI must implement correctly on its own.

Should AI Coding Agents Have Access to Production?

No. Give agents access to local or staging environments only, keep production credentials out of their reach, and require human approval for destructive actions.

The Bottom Line

Vibe coding security isn’t about avoiding AI. It’s about understanding where AI-generated code tends to fail and checking those areas every time: ownership checks, database rules, secrets, dependencies, input handling, and agent permissions.

Run the checklist, add tests that prove users can’t access one another’s data, and build on a framework with secure defaults. You can keep the speed of vibe coding without becoming the subject of the next security incident report.
