Lovable Security Review
Manual security audit by senior engineers. We trace every auth path, every secret, and every integration in your Lovable app and tell you what's broken.

Security issues we find in Lovable apps
Patterns documented in primary-source research. Most of these ship to production by default.
Supabase RLS disabled or misconfigured
CVE-2025-48757 disclosed 170+ Lovable apps with 303 endpoints exposing private data. 89% of scanned apps had no working Row Level Security. The AI assistant routinely creates tables without ENABLE ROW LEVEL SECURITY, or writes policies that grant the anon role full read/write.
Secrets inlined into the client bundle
Stripe secret keys, Resend API keys, and Supabase service role keys have all been observed leaking into dist/. Lovable inlines values meant for Edge Functions into the React client when prompt phrasing is ambiguous.
Stripe webhooks without signature verification
AI-generated webhook handlers trust the request body without calling stripe.webhooks.constructEvent, allowing payment bypass via forged events. Documented across multiple security writeups.
Public checkout endpoints with overridable amounts
Edge functions accept the price or amount from the client instead of looking it up server-side from a product ID. Customers can change the value before submitting.
Edge Function CORS + verify_jwt mismatch
Auth flows fail with 401 'Missing authorization header' because verify_jwt is left on for webhook endpoints. The AI's typical fix is to disable JWT verification entirely, removing all auth.
Regression loops that consume credits
Users report the AI re-introducing previously fixed bugs while consuming credits, often because Lovable doesn't read the full file before editing.
Missing security headers
No Content-Security-Policy, no X-Frame-Options, no Strict-Transport-Security on the static-hosted frontend. Clickjacking and MITM mitigations absent by default.
What a Lovable Security Review covers
Frequently asked questions
- Are Lovable apps secure by default?
- No. Independent research (CVE-2025-48757) found 89% of scanned Lovable apps lacked working Row Level Security on Supabase, exposing user data via the public anon key. Lovable's AI assistant doesn't reliably enable RLS or write correct policies.
- Can I migrate my Lovable app to my own infrastructure?
- Yes. The frontend exports to GitHub, but the Supabase database, Auth, Storage, and Edge Functions need to be rebuilt or migrated manually. We handle the full migration to Next.js + Supabase or other stacks for $400+.
- Why does my Lovable app keep burning credits?
- The 'Attempt Fix' loop re-sends your full project context on each retry. A single CORS or RLS bug the AI can't debug can consume hundreds of thousands of tokens. We fix these manually so you stop bleeding credits.
- Do you offer ongoing support after the audit?
- Yes. We offer a Retainer from $250/mo that covers ongoing bug fixes, feature work, and code reviews so your Lovable app stays maintained as you scale.
