Prototype Security Audit

Is your vibe-coded appsafe to launch?

AI builders get you a working demo fast — and ship the same security holes again and again. Before you put real users (and real data) behind it, check these.

Are AI-built apps secure?

Usually not by default. Apps generated in Lovable, Bolt, v0, Cursor, and Replit commonly ship with the same failure mode: missing database row-level security and exposed Supabase / API keys. Independent research in 2025–2026 (CVE-2025-48757; a January 2026 SupaExplorer analysis) documented this at scale. The fix is a security audit and hardening before launch.

The vibe-coding security checklist

  • Row-level security (RLS). Tables readable/writable by any user because RLS was never enabled or is misconfigured.
  • Exposed API / anon keys. Secret keys hardcoded in client code or committed to the repo, usable by anyone who views source.
  • Unprotected endpoints. API routes that trust the client and skip server-side authorization checks.
  • Auth gaps. Weak session handling, missing email verification, or roles that can be bypassed.
  • Payment integrity. Subscription/paywall logic enforced only on the client, so it can be skipped.
  • Rate limiting & abuse. No throttling — runaway API usage and billing spikes from bots or attackers.

Why this keeps happening

Security lives in the last 30% of a build — the part AI tools handle worst. Row-level security, key management, and server-side authorization are system-wide concerns that an AI assistant loses track of between prompts. The result is an app that looks finished and demos perfectly, while leaving the database open underneath.

FAQ

Are apps built with Lovable, Bolt, or Cursor secure by default?

Not reliably. Independent research has repeatedly found the same failure mode across AI builders — missing row-level security and exposed anon/API keys. In 2025, the CVE-2025-48757 disclosure documented missing-RLS exposure across a large sample of Lovable-built apps, and a January 2026 analysis (SupaExplorer) found roughly 11% of vibe-coded apps leaking Supabase keys. The tools are improving, but security is not automatic.

What is the most common vibe-coding security hole?

Missing or misconfigured row-level security on the database, followed by exposed keys in client code. Both let an outsider read or modify data they should never touch — often without any obvious sign in the app itself.

Is AI-generated code more vulnerable than hand-written code?

On average it carries more security issues. Veracode found roughly 45% of AI-generated code samples contained an OWASP Top-10 weakness, and other analyses report AI-generated code introducing more cross-site-scripting (XSS) issues than human-written baselines. It is shippable — but it needs hardening before real users.
