Prbl for apps built with Lovable

Lovable gets you to a working full-stack app fast, usually on a Supabase backend. That is also where the risk concentrates: Row Level Security and exposed keys. Prbl checks for exactly that.

By Prbl Security Team

Lovable is great at turning a prompt into a running app. What it does not do is stop and ask whether the database it wired up is actually locked down. Because Lovable apps lean on Supabase, the single most important question is whether Row Level Security is on for every table, since the anon key that ships to the browser is public by design.

What tends to go wrong in Lovable apps

  • Supabase tables with Row Level Security off, readable by anyone with the public anon key
  • Keys or config exposed in the frontend bundle
  • Missing authorization checks on generated data access
  • Fallback secrets in environment lookups that become predictable production secrets

We scanned real AI-built apps and many exposed a Supabase anon key, with more than one in four of those having at least one table anyone could read. The full breakdown is in the open database study.

Scan your own app for issues like these

Paste your live URL. We check what your app serves publicly for exposed keys and misconfigurations. No account, no install.

The fastest check

Start with the free Supabase RLS checker: paste your Lovable app URL and see whether it exposes a key and what that means. Then run a full scan for the rest, and follow the RLS checklist for AI apps to close the gaps.

Frequently asked questions

What's the single most important thing to check in a Lovable app?

Whether Row Level Security is on for every Supabase table. Lovable apps ship a public anon key by design; RLS is what decides whether that key can read your whole database or nothing.

How common is an exposed Supabase issue in Lovable apps?

In our study of real AI-built apps, more than one in four Supabase-backed apps we checked had at least one table anyone could read with no login.

What's the fastest way to check a Lovable app specifically?

Start with the free Supabase RLS checker: paste your Lovable app URL and see whether it exposes a key and what that means, then run a full scan for the rest.
