Use this checklist to ensure your Lovable application is secure before launch. 5 critical items require immediate attention.
Row Level Security must be enabled on every Supabase table
Users should only read their own data
Prevent unauthorized data modification
Verify policies work by querying without auth
No OpenAI, Stripe, or other keys in source code
All secrets should be in .env files
Supabase service key must never be in frontend
Require users to confirm email before access
Minimum length and complexity rules
Prevent brute force attacks on auth endpoints
Prevent XSS and injection attacks
Force HTTPS connections
Prevent clickjacking attacks
Prevent MIME sniffing
VAS automatically checks 12 of these 14 items. Get instant results with detailed remediation guidance.
Run Automated Security ScanVAS can automatically check 11 of the 14 items on the Lovable security checklist, including all RLS configurations, exposed API keys, security headers, and authentication settings. The remaining 3 items require manual verification.
The 7 critical items are all related to database security (RLS policies) and secret management. Missing RLS was the root cause of CVE-2025-48757, which affected 170+ Lovable apps. Start with these before addressing high/medium items.
For a typical Lovable app, expect 30-60 minutes for the full checklist. RLS policy writing takes the longest. Running a VAS scan first helps prioritize - it identifies which items are already passing and which need attention.
