 🔴 CRITICAL: DATABASE CONNECTION STRING EXPOSED
═══════════════════════════════════════════════════════════

 Severity: P0 - CRITICAL
 Status: ❌ PostgreSQL connection string found in client code!

 ⚠️  IMMEDIATE ACTION REQUIRED ⚠️

 Connection String:
 postgresql://postgres:MySecr***@db.abc123def.supabase.co:5432/postgres
 (Password partially redacted in display, full value in context file)

 Parsed Components:
 ├── Host: db.abc123def.supabase.co
 ├── Port: 5432
 ├── Database: postgres
 ├── Username: postgres
 └── Password: [EXPOSED] ← CRITICAL

 Location:
 └── /static/js/api.chunk.js (line 234)
     const DATABASE_URL = 'postgresql://postgres:...'

 Impact Assessment:
 ├── 🔴 Direct PostgreSQL access possible
 ├── 🔴 All RLS policies bypassed
 ├── 🔴 Can access auth.users table
 ├── 🔴 Can modify database schema
 └── 🔴 Full data exfiltration possible

 ═══════════════════════════════════════════════════════════
 IMMEDIATE REMEDIATION STEPS
 ═══════════════════════════════════════════════════════════

 1. CHANGE DATABASE PASSWORD NOW
    → Supabase Dashboard > Settings > Database > Reset database password

 2. REMOVE FROM CLIENT CODE
    → Delete connection string from source code
    → Ensure DATABASE_URL is not in NEXT_PUBLIC_* or VITE_* env vars
    → Redeploy application

 3. AUDIT FOR ABUSE
    → Check Supabase logs for direct PostgreSQL connections
    → Review for unauthorized data access or modifications

 4. USE PROPER ARCHITECTURE
    → Client should ONLY use Supabase client library (REST API)
    → Direct DB access should ONLY be from:
      - Edge Functions
      - Server-side code
      - Migration tools

 Found:

 Recommendation:
 → Rotate database password as precaution
 → Remove all DB-related values from client code
