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

Report Structure

The generated report includes:

1. Executive Summary — High-level overview for management
2. Security Score — Quantified risk assessment
3. Critical Findings (P0) — Immediate action required
4. High Findings (P1) — Address soon
5. Medium Findings (P2) — Plan to address
6. Detailed Analysis — Per-component breakdown
7. Remediation Plan — Prioritized action items
8. Appendix — Technical details, methodology

# 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

 Key Management
 9.8 (Critical)



The Supabase service

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

```bash
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
  // ...
})

Documentation:

• Supabase API Keys
• Edge Functions

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

MANDATORY: Context File Dependency

⚠️ This skill REQUIRES properly populated tracking files.

Prerequisites

Before generating a report, ensure:

1. .sb-pentest-context.json exists and contains findings from audit skills
2. .sb-pentest-audit.log exists with timestamped actions
3. All relevant audit skills have updated these files

If Context Files Are Missing

If context files are missing or empty:

1. DO NOT generate an empty report
2. Inform the user that audit skills must be run first
3. Recommend running supabase-pentest for a complete audit

Report Generation Output

After generating the report, this skill MUST:

1. Log to .sb-pentest-audit.log:

   [TIMESTAMP] [supabase-report] [START] Generating security report
   [TIMESTAMP] [supabase-report] [SUCCESS] Report generated: supabase-audit-report.md
   [TIMESTAMP] [supabase-report] [CONTEXT_UPDATED] Report generation logged
   

2. Update .sb-pentest-context.json with report metadata:

   {
     "report": {
       "generated_at": "...",
       "filename": "supabase-audit-report.md",
       "findings_count": { "p0": 3, "p1": 4, "p2": 5 }
     }
   }
   

FAILURE TO UPDATE CONTEXT FILES IS NOT ACCEPTABLE.
