Technical Deep Dive

Supabase abstracts away much of the complexity of building a backend, but it shifts the security burden directly to the database. Row Level Security (RLS) is your primary defense line. A single misconfigured policy can expose your entire user base. DBX analyzes your Postgres schema, functions, and policies to ensure that authenticated users can only access their own data, and unauthenticated 'anon' users have zero access to sensitive tables.

  • 01
    Public table exposure
  • 02
    Cross-tenant data leaks
  • 03
    RPC privilege escalation

Audit Checklist

Enable RLS on every table in the 'public' schema
Verify 'anon' role has zero permissions on private tables
Audit SECURITY DEFINER functions for search_path vulnerabilities
Check storage.objects RLS for public bucket exposure
Validate auth.uid() checks in every policy predicate

How it works

High-integrity schema introspection

Introspect

Run a read-only script to extract your database catalog. No data ever leaves your machine.

Simulate

Our engine executes billion-path simulations to find logical RLS bypasses.

Remediate

Receive copy-paste SQL fixes for every high-risk vulnerability discovered.
