Technical Deep Dive

A Row Level Security policy is only as good as its SQL predicate. Many developers use 'USING (true)' during development and forget to tighten it. DBX performs deep analysis of your policy expressions, identifying common mistakes like using the wrong role check, missing authenticated user filters, or creating recursive policies that crash your database.

Formal policy verification

Syntax-aware logic checks

Primary Vulnerability Vectors

01
Logical policy bypass
02
Infinite recursion errors
03
Performance degradation

Audit Checklist

Scan for 'USING (true)' in production policies

Validate auth.uid() vs user_id equality checks

Check for recursive policy definitions

Audit policy performance for deep table trees

Verify SELECT/INSERT/UPDATE/DELETE coverage

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.
