Supabase Security

Supabase Security Scanner

Using Supabase? Make sure your Row Level Security is properly configured. We test your actual database to find exposed tables.

Our automated security scanner analyzes your Supabase application for vulnerabilities, misconfigurations, and exposed secrets. Get a comprehensive security report in minutes, not days.

Most Supabase Security Issues: Missing RLS

The majority of Supabase security incidents stem from tables without Row Level Security enabled. When RLS is disabled, anyone with your anon key can read, modify, or delete all data in that table.

Supabase Security Considerations

Supabase makes development fast, but AI-generated code often skips security best practices:

  • !Tables without Row Level Security enabled
  • !RLS policies that are too permissive
  • !Service role key exposed in client code
  • !RPC functions callable without authentication

What We Check

RLS Policies

Tests your Row Level Security by attempting to read/write data as anonymous and authenticated users.

Service Key Exposure

Scans for service_role keys that should never be in client-side code.

RPC Functions

Tests your database functions for proper authentication requirements.

Auth Configuration

Checks authentication settings for weak passwords, missing verification, and rate limiting.

What You'll Get

RLS policy audit report
Exposed tables list with SQL
RPC function security check
Service key exposure scan
Auth configuration review
Copy-paste RLS policies
AI-ready markdown export
Re-scan after fixes

Why Supabase Apps Need Security Scanning

Supabase provides a powerful PostgreSQL database with built-in authentication and real-time subscriptions. However, its security model relies on Row Level Security (RLS) policies that you must configure explicitly for each table.

By design, Supabase exposes your project URL and anon key in client-side code. This is intentional and secure IF you have proper RLS policies. Without RLS, anyone with these public credentials can access your entire database.

VAS actively tests your Supabase configuration by querying your tables with the anon key. We identify which tables are exposed, which RLS policies are missing or misconfigured, and provide the exact SQL to fix each issue.

How Supabase Security Scanning Works

2

Automated Analysis

We scan for exposed secrets, security headers, authentication issues, database misconfigurations, and Supabase-specific vulnerabilities. The scan typically completes in 15-20 minutes.

3

Get Actionable Results

Receive a detailed report with prioritized vulnerabilities, severity ratings, and step-by-step remediation guidance with code examples specific to Supabase.

Common Questions About Supabase Security

What vulnerabilities are most common in Supabase apps?

The most frequent issues we find include exposed API keys in frontend code, missing or misconfigured authentication, insecure database access patterns, and missing security headers. These often result from AI-generated code that prioritizes functionality over security.

How long does a security scan take?

Most Supabase application scans complete within 15-20 minutes. Larger applications with many pages may take slightly longer. You'll receive an email notification when your scan is ready.

Will the scan affect my production app?

Our scanner uses non-invasive techniques and won't modify your application or data. We analyze your publicly accessible endpoints, check security configurations, and look for exposed secrets without performing destructive tests.

Secure Your Supabase App

Don't let vulnerabilities compromise your hard work. Security issues in Supabase applications can lead to data breaches, unauthorized access, and damaged user trust.
