Lovable App Security Checklist: 12 Checks Before You Publish
Before publishing your Lovable app, verify these 12 security checks covering Row Level Security, API key management, authentication, and data protection. Each check is ranked by severity so you know what to fix first.
Fix first
6 checksRow Level Security (RLS) is enabled on all Supabase tables
This is the single most critical security check. Without RLS, your database tables are publicly accessible through the Supabase API. Open the SQL editor and run: SELECT tablename, rowsecurity FROM pg_tables WHERE schemaname = 'public'; Every table with user data must show true.
RLS policies use auth.uid(), not client-provided IDs
RLS policies must use auth.uid() to identify the current user. Never trust user IDs sent from the client. A policy like USING (user_id = auth.uid()) ensures each user can only access their own data.
Service role key is not used in frontend code
The Supabase service role key bypasses all RLS policies. It must only appear in Edge Functions (server-side). Search your entire codebase for your service role key string to verify it is not exposed.
All API keys are stored in Lovable Secrets
Stripe keys, OpenAI keys, and any third-party credentials must be stored in Lovable Secrets, not hardcoded in your source files. Lovable warns you when you paste keys in chat, but always double-check the generated code.
Authentication flow requires email confirmation
Enable email confirmation in your Supabase Auth settings. Without it, anyone can create accounts with fake emails and access your app. This is a basic spam prevention measure.
Protected routes redirect unauthenticated users
Every page that shows user data must check for a valid session. Open an incognito window and navigate directly to /dashboard, /settings, or any authenticated route. If it renders without login, you have a gap.
Important
3 checksINSERT/UPDATE policies include WITH CHECK clause
Without WITH CHECK, users may be able to insert rows they should not own. Every INSERT and UPDATE RLS policy should include WITH CHECK (user_id = auth.uid()).
Security View has been reviewed before publishing
Lovable's built-in Security View aggregates findings from its database advisor and code review. Open it and address all Error and Warning items before publishing.
CORS is configured to allow only your domain
Check that your Supabase project only allows requests from your app's domain, not from any origin. This prevents other websites from making API calls with your users' credentials.
Recommended
3 checksError messages do not expose system details
Trigger errors in your app and check what users see. Stack traces, database error messages, and file paths should never be visible in production. Show generic error messages instead.
Rate limiting is configured on auth endpoints
Without rate limiting, attackers can brute-force passwords or spam signup. Supabase has built-in rate limits, but verify they are active in your project settings.
An on-demand security review has been run
Prompt Lovable with "review my app's security" to trigger a full codebase analysis. This catches patterns that the default Security View might miss.

Frequently asked questions.
About 30 minutes for a thorough manual review. Automated tools like BWORLDS can run these checks in under 5 minutes.
Yes. Each time you add new tables, routes, or integrations, re-run the security checks. New AI-generated code can introduce new gaps.
This covers the baseline. Enterprise clients may also require SOC 2 compliance, penetration testing, or a formal security policy. But passing this checklist prevents the most common deal-killing issues.
Missing Row Level Security (RLS) policies on Supabase tables. When Lovable generates database tables, RLS may not be enabled or may have overly permissive policies. Without proper RLS, anyone with your Supabase project URL and anon key can read, modify, or delete data in unprotected tables. This is the single most critical check in this list.
Yes. BWORLDS runs automated security scans that cover all 12 checks in this list plus additional patterns specific to AI-built apps. The scan takes under 5 minutes and generates a pass/fail report you can share with clients or stakeholders. It also monitors for regressions as you publish updates.
Fix it before publishing. For missing RLS, enable it on the affected tables and add proper policies. For exposed API keys, rotate them immediately and move them to Lovable Secrets. For missing auth on routes, add session checks. Each critical fix typically takes 15-30 minutes. Do not publish with known critical issues.
