Is my Lovable app secure?
A Lovable app is as secure as its Supabase rules. The builder produces a working front end quickly; the protection of your data depends on row level security policies that have to be right for every table.
A Lovable app can be secure, but most of the risk lives in the Supabase project behind it, not in the interface you see. The front end talks to the database directly with a public key, so any table without correct row level security (RLS) policies can be read or changed by anyone who opens the browser developer tools. Check every table's policies before launch, keep any secret key server-side in an edge function, and have the app tested once real personal information or payments are involved.
Where the risk sits in a Lovable app
Lovable generates a React front end wired to Supabase. That design is sound: the anon key is meant to be public, and the database decides what each request may do. It only works if RLS is on for every table and each policy says what you mean. A public vulnerability record, CVE-2025-48757, describes exactly this failure in Lovable-generated projects: insufficient RLS policies that let unauthenticated requests read or write data. Lovable has since added a security scan. It helps, and it does not know your business rules.
| Finding | How to check it yourself |
|---|---|
| RLS disabled on a table | In Supabase, Table Editor: every table should show RLS enabled |
| Policies that allow everyone | Look for policies using true for select, insert or update |
| Policies checking the wrong column | Log in as user A and request user B's row by ID from the browser console |
| Service role key in the front end | Search the built JavaScript for service_role or a key starting eyJ with a service role claim |
| Storage buckets set to public | Storage settings: private data should be in private buckets with policies |
| Edge functions without auth checks | Call the function URL without a session and see what it returns |
| Third-party keys in client code | Search the bundle for sk_, OpenAI and email provider keys |

The tool is not the problem
Lovable produces working software quickly and it is a reasonable way to build a first version. Its output is a first draft. Nothing in the tool checks that every record is protected from every user who should not see it, because that depends on rules only you know. Ask it to add the checks, then have someone who did not write the prompts verify them. That is what a security test is.
Getting it tested
A security and QA test of a small Lovable app typically costs $2,000 to $12,000 CAD, depending on roles, payments and any AI features. Testers work from the running app and, if you share it, the exported code. See what to give the testers.

Common questions
Does Lovable's built-in security scan replace a test?
No. It catches common configuration problems, which is useful. It cannot know which users should see which records in your product, and that is where the serious findings are.
Is the Supabase anon key a secret?
No. It is designed to be public. The protection comes from RLS policies, which is why they have to be correct on every table.
Can I export my Lovable code for review?
Yes, through its GitHub integration. Giving testers the code shortens the test and makes findings more precise.
