Is my Lovable app secure?

Lovable builds a working React app from a chat. It is excellent at screens and flows and silent about security, because nothing in the prompt asked for it. The three gaps below show up in most Lovable apps we see.

What Lovable usually leaves open

Typical stack: React + Vite front end, usually Supabase for auth and data, deployed on Lovable hosting or exported to Vercel/Netlify.

Row-level security disabled or policy allows everyone (Code Scan)Row-level security off or a policy that says using (true). The anon key is in the browser by design, so every table without RLS is public.
Secret exposed through a browser-public env prefix (Code Scan)A secret pasted into a VITE_ variable. Anything with that prefix is bundled into the JavaScript every visitor downloads.
Server-only key referenced in client code (Code Scan)The Supabase service-role key used in front-end code to 'fix' a permission error. It bypasses RLS entirely.
Content Security Policy (CSP)No Content-Security-Policy and no HSTS on the hosted site, so an injected script runs with full access.
Auth token stored in localStorage (Code Scan)Session tokens kept in localStorage, readable by any script on the page.

How to fix it in Lovable

Run the scan, then paste this into Lovable together with the Kavach report. It tells the assistant exactly what to do and what not to touch.

Paste into Lovable

Review this project for security before launch. 1) Enable row-level security on every Supabase table the anon key can reach and write policies that compare auth.uid() to the owner column; show me each policy. 2) Find every VITE_ variable that holds a secret and move the call that uses it into a Supabase Edge Function. 3) Remove any use of the service_role key from client code. 4) Add Content-Security-Policy and Strict-Transport-Security headers. Explain each change and do not remove features.

Re-scan when it is done. The grade and the findings list show whether the change took, and monitoring tells you if a later prompt reopens anything.

Questions about Lovable security

Is a Lovable app secure by default?

Not on its own. Lovable produces working code quickly, but security controls such as row-level security policies, a Content-Security-Policy and secret handling only exist if someone asks for them. Kavach's live-site audit and Code Scan show which of them are missing on your app.

Why is my Supabase anon key visible in the browser?

That is normal: the anon key is meant to be public. What protects your data is row-level security on every table. If RLS is off or a policy allows everyone, the public key reads everything.

How do I scan my Lovable app with Kavach?

Paste the live URL on the home page with the AI-built profile for the external audit. For the code, use Lovable's GitHub export, download the repository as a zip and upload it to Code Scan.

Can Kavach fix the issues for me?

Kavach gives you a remediation prompt and, on each finding, an AI second opinion with a draft fix. Paste the prompt back into Lovable's chat; it applies the changes, then re-scan to confirm.
