Supabase Report

Security Report Generator

🔴 CRITICAL: PROGRESSIVE FILE UPDATES REQUIRED You MUST write to context files AS YOU GO, not just at the end. - Write to .sb-pentest-audit.log IMMEDIATELY as you process each section - Update .sb-pentest-context.json with report metadata progressively - DO NOT wait until the entire report is generated to update files - If the skill crashes or is interrupted, the partial progress must already be saved This is not optional. Failure to write progressively is a critical error.

This skill generates a comprehensive Markdown security audit report from all collected findings.

When to Use This Skill

• After completing security audit phases
• To document findings for stakeholders
• To create actionable remediation plans
• For compliance and audit trail purposes

Prerequisites

• Audit phases completed (context file populated)
• Findings collected in .sb-pentest-context.json

# Supabase Security Audit Report

**Target:** https://myapp.example.com
**Project:** abc123def.supabase.co
**Date:** January 31, 2025
**Auditor:** Internal Security Team

## Executive Summary

### Overview

This security audit identified **12 vulnerabilities** across the Supabase implementation, including **3 critical (P0)** issues requiring immediate attention.

### Key Findings

| Severity | Count | Status |
|----------|-------|--------|
| 🔴 P0 (Critical) | 3 | Immediate action required |
| 🟠 P1 (High) | 4 | Address within 7 days |
| 🟡 P2 (Medium) | 5 | Address within 30 days |

### Security Score

**Score: 35/100 (Grade: D)**

The application has significant security gaps that expose user data and allow privilege escalation. Critical issues must be addressed before the application can be considered secure.

### Most Critical Issues

1. **Service Role Key Exposed** — Full database access possible
2. **Database Backups Public** — All data downloadable
3. **Admin Function No Auth** — Any user can access admin features

### Recommended Actions

1. ⚡ **Immediate (Today):**
   - Rotate service role key
   - Make backup bucket private
   - Add admin role verification

2. 🔜 **This Week:**
   - Enable RLS on all tables
   - Enable email confirmation
   - Fix IDOR in Edge Functions

3. 📅 **This Month:**
   - Strengthen password policy
   - Restrict CORS origins
   - Add rate limiting to functions

## Critical Findings (P0)

### P0-001: Service Role Key Exposed in Client Code

**Severity:** 🔴 Critical
**Component:** Key Management
**CVSS:** 9.8 (Critical)

#### Description

The Supabase service_role key was found in client-side JavaScript code. This key bypasses all Row Level Security policies and provides full database access.

#### Location

File: /static/js/admin.chunk.js Line: 89 Code: const SUPABASE_KEY = 'eyJhbGciOiJIUzI1NiI...'

#### Impact

- Full read/write access to all database tables
- Bypass of all RLS policies
- Access to auth.users table (all user data)
- Ability to delete or modify any data

#### Proof of Concept

curl 'https://abc123def.supabase.co/rest/v1/users' \ -H 'apikey: [service_role_key]' \ -H 'Authorization: Bearer [service_role_key]'

Returns ALL users with full data

#### Remediation

**Immediate:**
1. Rotate the service role key in Supabase Dashboard
   - Settings → API → Regenerate service_role key
2. Remove the key from client code
3. Redeploy the application

**Long-term:**

// Move privileged operations to Edge Functions // supabase/functions/admin-action/index.ts

import { createClient } from '@supabase/supabase-js'

Deno.serve(async (req) => { // Service key only on server const supabase = createClient( Deno.env.get('SUPABASE_URL')!, Deno.env.get('SUPABASE_SERVICE_ROLE_KEY')! )

// Verify caller is admin before proceeding // ... })

### P0-002: Database Backups Publicly Accessible

**Severity:** 🔴 Critical
**Component:** Storage
**CVSS:** 9.1 (Critical)

#### Description

The storage bucket named "backups" is configured as public, exposing database dumps, user exports, and environment secrets.

#### Exposed Files

| File | Size | Content |
|------|------|---------|
| db-backup-2025-01-30.sql | 125MB | Full database dump |
| users-export.csv | 2.3MB | All user data with PII |
| secrets.env | 1KB | API keys and passwords |

#### Impact

- Complete data breach (all database content)
- Exposed credentials for third-party services
- User PII exposed (emails, names, etc.)

#### Remediation

**Immediate:**

-- Make bucket private UPDATE storage.buckets SET public = false WHERE name = 'backups';

-- Delete or move files -- Consider incident response procedures

**Credential Rotation:**
- Stripe API keys
- Database password
- JWT secret
- Any other keys in secrets.env

### P0-003: Admin Edge Function Privilege Escalation

**Severity:** 🔴 Critical
**Component:** Edge Functions
**CVSS:** 8.8 (High)

#### Description

The `/functions/v1/admin-panel` Edge Function is accessible to any authenticated user without role verification.
