Common issues
Top vulnerabilities in Lovable apps
These are the three most common security issues we find when scanning Lovable projects.
Supabase tables with no Row Level Security, letting anyone read your data
API keys and secrets exposed in client-side JavaScript bundles
Missing security headers like CSP and HSTS on your deployed app

Fix guides for Lovable
Common Lovable security fixes
Supabase RLS disabled
A Supabase table without RLS is readable (and often writable) by anyone with your anon key. Here is exactly how to turn on RLS and write your first policy.
Read moreExposed Supabase service key
The service role key bypasses all security in Supabase. If it is in your client code, an attacker has full database access. Here is how to find and fix it.
Read moreHardcoded API key in JS
Any secret in your client bundle is public. Here is how to find them, rotate them, and move the calls server-side.
Read moreMissing CSP header
A missing Content-Security-Policy header lets attackers inject scripts into your site. Here is what CSP does, why you need it, and how to add it in Next.js, Vercel, and Supabase apps.
Read moreMissing HSTS header
HSTS tells browsers to always use HTTPS for your site. Without it, users can be downgraded to HTTP and have sessions stolen. Here is how to add HSTS on Vercel, Next.js, and other hosts.
Read moreExposed .env file
An exposed .env file is a critical leak — it contains API keys, database URLs, and secrets. Here is why it happens in vibe-coded apps and how to lock it down.

Lovable security FAQ
- How do I fix Supabase RLS issues in a Lovable app?
- Tell Lovable: 'Enable Row Level Security on every public table and add policies so users can only read and modify their own rows. Use auth.uid() = user_id for ownership checks.' Lovable will generate the SQL migrations for you.
- Can I use the Supabase service role key in Lovable?
- Only in server-side functions, never in client code. If Lovable has generated frontend code that uses the service role key, prompt it to move those calls to a serverless function and use the anon key + RLS in the client.
- What does a secure Lovable deployment look like?
- Three things: (1) RLS on with explicit policies on every Supabase table; (2) no service role keys or third-party API keys in the frontend bundle; (3) security headers set via the deployment platform (Vercel, Netlify). SafeToShip checks all three.
