Is Lovable Safe?

Last updated: January 12, 2026

An honest security analysis of Lovable for developers considering it for their projects.

Quick Answer

Safe with caution - requires Supabase RLS configuration

Lovable is generally safe to use, but apps built with it require security review. A critical RLS vulnerability (CVE-2025-48757) affected 170+ apps in January 2025, exposing data across 303 vulnerable API endpoints. Lovable exclusively uses Supabase as its backend, so your app's security depends entirely on proper RLS configuration.

Known Security Incidents

CVE-2025-48757: Mass RLS Misconfiguration

January 2025

Security researchers discovered 303 vulnerable API endpoints across 170+ Lovable apps. Attackers could read user emails, passwords, payment data, and even admin credentials. Some apps had service_role keys exposed, allowing full database takeover.

Security Assessment

Security Strengths

  • Built-in 'Security Scan' feature in Lovable dashboard alerts you to RLS issues
  • Uses Supabase exclusively - single backend means focused security review
  • Deploys to Vercel/Netlify with automatic HTTPS and CDN protection
  • Active team that issued guidance after CVE-2025-48757 disclosure
  • Generates TypeScript React code with type safety

Security Concerns

  • CVE-2025-48757 exposed 303 vulnerable endpoints across 170+ apps
  • Lovable AI creates Supabase tables WITHOUT enabling RLS by default
  • 83% of exposed Supabase databases involve RLS misconfigurations (Escape.tech)
  • Generated code often hardcodes OpenAI/Stripe keys in React components
  • No Firebase or other backend options - must learn Supabase security model

Security Checklist for Lovable

  • 1
    Run Lovable's built-in 'Security Scan' from the dashboard
  • 2
    Go to Supabase → Authentication → Policies and enable RLS on EVERY table
  • 3
    Write SELECT/INSERT/UPDATE/DELETE policies that check (select auth.uid()) = user_id
  • 4
    Search codebase for 'sk-' (OpenAI) and 'sk_live' (Stripe) - move to Supabase Edge Functions
  • 5
    Check that service_role key is NOT in any frontend files
  • 6
    Test RLS: run SELECT * FROM your_table; as anonymous in SQL editor - should return 0 rows

The Verdict

Lovable makes building apps incredibly fast, but the January 2025 CVE-2025-48757 incident proved that speed without security review is dangerous. Use Lovable's built-in Security Scan, enable RLS on every Supabase table, and run VAS before launching. The Supabase-only architecture means you only need to master one security model.

What Security Experts Say

There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.

It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.

Frequently Asked Questions

Is Lovable safe for production apps?

Lovable can be used for production apps, but requires security review before launch. The CVE-2025-48757 incident showed that default configurations are not production-ready. Use Lovable's built-in Security Scan feature and enable RLS on all Supabase tables.

What was the Lovable security vulnerability (CVE-2025-48757)?

CVE-2025-48757 was a mass RLS misconfiguration discovered in January 2025 that affected 170+ Lovable applications across 303 vulnerable endpoints. Attackers could read and write to Supabase databases, exposing user emails, API keys, payment information, and even admin credentials with service_role key access.

How do I secure my Lovable app?

To secure your Lovable app: 1) Run Lovable's built-in Security Scan from the dashboard, 2) Enable Row Level Security (RLS) on all Supabase tables in the Supabase dashboard, 3) Create policies using (select auth.uid()) = user_id pattern, 4) Move API keys to Supabase Edge Functions, 5) Test by querying as anonymous user.

Does Lovable expose my Supabase API keys?

Lovable apps include the Supabase anon key in frontend code, which is intentional and safe - the anon key is designed to be public. Security comes from Row Level Security (RLS) policies. However, NEVER expose the service_role key, which was found exposed in some CVE-2025-48757 affected apps.

Why does Lovable only use Supabase?

Lovable exclusively uses Supabase as its backend, which simplifies the development experience but means you must understand Supabase's security model. This is different from Bolt.new which supports multiple backends (Supabase, Firebase, etc.). The single-backend approach means focused security review.
