Security Audit for Lovable Apps
Lovable gets you from prompt to a working React and Supabase app fast. Before you collect real user data or payments, we review the parts Lovable generates but cannot reason about: who can read which rows, which keys reach the browser, and which rules only exist in the UI.

What we find most often in Lovable apps
Lovable apps share a predictable shape: a React front end talking directly to Supabase, plus edge functions for anything sensitive. The risks follow that shape.
Missing or permissive row-level security
Tables created during iteration can end up with RLS disabled or with policies such as `using (true)`. Because the front end queries Supabase directly with the public anon key, a permissive policy means any visitor can read or modify those rows.
Authorization enforced only in the UI
Hiding an admin button is not access control. If role checks live in React components rather than in RLS policies or edge functions, users can call the same queries from the browser console.
Secrets in client code or prompts
Third-party API keys pasted into prompts can end up in front-end code. Anything bundled into the browser is public, including keys for OpenAI, Stripe, or email providers.
Unverified payment webhooks
Stripe integrations sometimes grant access on a success redirect or accept webhook payloads without verifying the signature, so paid features can be unlocked without paying.
Edge functions without auth checks
Supabase edge functions that use the service role key bypass RLS entirely. If they do not verify the caller's JWT and ownership, they become an open door to every row.
Storage buckets left public
Uploaded documents, avatars, and exports stored in public buckets or with broad storage policies can be listed or fetched by anyone who guesses the path.
What a Lovable security audit covers
A fixed-scope review of your exported repository and Supabase project, delivered as a prioritized report with fixes you can paste back into Lovable.
Checks you can run yourself
Start here before you book anything. If any of these fail or you are not sure how to check, that is the signal to get a second pair of eyes.
- Open the Supabase dashboard and confirm RLS is enabled on every table in the public schema.
- Search policies for `using (true)` or `with check (true)` and confirm each one is intentional.
- Sign in as user A, copy a request from the network tab, and replay it with user B's session. You should not see A's data.
- Search your built JavaScript for `sk_`, `service_role`, and third-party API keys.
- Confirm paid access is granted only after a verified Stripe webhook, not on the checkout success page.
