Technical Deep Dive

Row Level Security is the bedrock of Supabase security, but it's easy to accidentally bypass. Common bypass vectors include views that are created without security settings, triggers that execute as SECURITY DEFINER, and missing policies on join tables. DBX's deterministic engine simulates request paths through your Supabase project to identify where an unauthenticated user could 'jump' around your RLS constraints and access unauthorized data.

  • 01
    Full database data exfiltration
  • 02
    Unauthorized record creation
  • 03
    Data integrity bypass

Audit Checklist

Verify RLS is enabled on all views and tables
Scan for SECURITY DEFINER triggers with public owners
Check for missing policies on 'many-to-many' join tables
Validate that 'authenticated' policies don't leak to 'anon'
Audit public RPC functions for RLS-bypassing logic

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.
