The Hidden Dangers of Lovable's Default Supabase Config
Lovable sets up Supabase fast — but the default configuration leaves security gaps. Here's what to check before you go live.
Lovable is incredible at getting you from zero to deployed in minutes. But the default Supabase configuration it generates is optimized for speed, not security.
What Lovable Generates
When Lovable provisions a Supabase project, it creates tables with basic RLS policies — often just auth.uid() = user_id. That's a start, but it's rarely sufficient for production.
Common Gaps
Open Storage Buckets
By default, storage buckets may allow public reads. If you're storing user uploads, profile images, or documents, this means anyone with the URL can access them.
Overly Permissive RLS
The generated policies often allow authenticated users to read all rows in a table. For multi-tenant apps, this means User A can see User B's data.
Missing Rate Limits
Supabase edge functions don't have rate limiting out of the box. A single bad actor can hammer your API and run up your bill.
How to Fix It
GetDeployable's security scanning catches these issues automatically. Our OWASP scanner runs against your staging environment before every production deployment, flagging:
- ›Open storage policies
- ›Overly broad RLS rules
- ›Missing authentication on edge functions
- ›Exposed environment variables in client bundles
Don't wait for a breach to think about security. Scan early, scan often.
