Supabase is powerful. Misconfiguration is where SaaS apps leak.
GhostCode reviews Supabase RLS, policies, storage, anon key assumptions, service role handling, Edge Functions, APIs, and permission boundaries.
Supabase security is usually about policy precision.
Supabase is not insecure by default. The common failure mode is a fast product with policies, buckets, and server routes built for momentum before they were threat-modeled.
RLS mistakes
RLS can be enabled but still too broad, too trusting, or inconsistent across tables.
Anon key confusion
The anon key is public by design. The risk is when policies behind it allow the wrong access.
Storage buckets
Public buckets, predictable paths, and weak signed URL assumptions can expose files.
Service role keys
Service role keys should never be shipped to browsers or client-visible bundles.
Edge Functions and APIs
Server-side routes still need authorization checks, validation, and scoped database access.
What GhostCode checks in a Supabase security audit.
- RLS policy review across sensitive tables
- Anon key exposure clarification and permission mapping
- Storage bucket visibility and signed URL assumptions
- Service role key handling and deployment risks
- Edge Functions, public APIs, and server-side permission boundaries
- Admin and support workflows that touch customer data
Before you scale traffic,make sure you are not scaling exposure.
