Why Supabase Apps Need Security Scanning
Supabase has become the default backend for vibe-coded applications, offering PostgreSQL, authentication, and real-time subscriptions out of the box. But its power comes with responsibility: Row Level Security (RLS) policies are essential for data protection, and AI-generated code often skips them entirely.
Research on Lovable-generated applications found that 10.3% had critical RLS flaws exposing user data. When RLS is disabled or misconfigured, anyone with your anon key can read, write, or delete any row in your database. The anon key is meant to be public - RLS is what keeps your data safe.
Common Supabase Security Issues
- RLS disabled entirely on tables
- RLS enabled but no policies defined
- Policies using auth.uid() without proper checks
- Exposed service_role keys in client code
- Missing policies on storage buckets
- Insecure Edge Functions without auth checks
- Database webhooks without verification
- Overly permissive policy conditions
Why Vibe-Coded Supabase Apps Are Vulnerable
Supabase defaults to RLS disabled for new tables, assuming developers will enable and configure it. AI coding tools generate database schemas and CRUD operations without mentioning RLS. The result: fully functional apps with zero data protection. Your frontend might have beautiful auth UI, but your database is wide open.
What VibeCheck Scans For
- RLS enabled status on all tables
- Policy coverage and correctness
- Service role key exposure in code
- Storage bucket RLS policies
- Edge Function authentication
- Database webhook security
- Anon key usage and exposure
- Policy condition security analysis
