Is your Lovable app secure? How to check in 2 minutes
AI coding tools ship fast — and they ship a recurring set of security holes. Here's the 2-minute check, and how to fix the big ones.

Why AI-built apps leak
Tools like Lovable, Bolt, v0 and Cursor are brilliant at getting an app running. But they optimize for 'it works,' not 'it's safe' — and the person shipping often can't read the code well enough to know the difference.
Research in 2026 found that roughly half of AI-generated code contains a known vulnerability, and that AI-generated code is now behind about one in five enterprise security incidents. The failures aren't random — they cluster around two things: secrets that end up in the browser, and backends that were never locked down.
The 2-minute check
1. Open your live app, right-click, and choose 'View Page Source' or open DevTools (F12) → Network → reload, and look at the JavaScript files. Search them for 'sk_live', 'sk-', 'AKIA', or 'service_role'. If you find any of those, a secret key is exposed.
2. Look for a Supabase URL (something.supabase.co) or a Firebase config. If your app talks to one of these directly from the browser, your data is only as safe as your access rules — which AI tools frequently leave wide open.
3. Or skip the manual hunt: paste your app's URL into VibeShield and it does all of the above in about 30 seconds, with a plain-English fix for anything it finds.
The fixes that matter most
Exposed secret keys: move every secret (Stripe sk_live, OpenAI, AWS, Supabase service_role) out of the browser and into a server route that reads them from environment variables. Then rotate the exposed key — assume it's already compromised.
Open database: if you use Supabase, turn on Row Level Security for every table and write policies so a user can only see their own rows. If you use Firebase, replace any 'test mode' rules with rules that require authentication.
The good news: these are fixable in minutes, and you can paste VibeShield's fix prompts straight into Cursor or Lovable to apply them.
Frequently asked questions
- Is it safe to have a Supabase anon key in my frontend?
- Yes — the anon key is designed to be public. The danger isn't the key; it's whether Row Level Security is enabled behind it. With RLS off, that public key can read your whole database.
- Does VibeShield see my code?
- No. It only reads the files your app already serves publicly to every visitor's browser. There's no login and no code upload.
Don't guess — scan it
VibeShield checks your live app for exposed keys and open databases in about 30 seconds, and hands you the fixes.
