 AUTHENTICATED USER AUDIT

 ─────────────────────────────────────────────────────────
 Test User Creation
 ─────────────────────────────────────────────────────────

 Status: ✅ User created successfully

 Test User Details:
 ├── Email: pentest-a7b3c9d2@security-audit.local
 ├── User ID: 550e8400-e29b-41d4-a716-446655440099
 ├── Password: [Saved to evidence - shown once]
 └── JWT obtained: ✅

 ─────────────────────────────────────────────────────────
 Anonymous vs Authenticated Comparison
 ─────────────────────────────────────────────────────────

 Table: users
 ├── Anonymous access: 0 rows
 ├── Authenticated access: 1,247 rows ← ALL USERS!
 └── Status: 🔴 P0 - Data hidden from anon but exposed to any auth user

 Table: orders
 ├── Anonymous access: 0 rows (blocked)
 ├── Authenticated access: 1 row (own orders only)
 └── Status: ✅ RLS working correctly

 Table: profiles
 ├── Anonymous access: 0 rows
 ├── Authenticated access: 1,247 rows ← ALL PROFILES!
 ├── Own profile only expected: ❌ NO
 └── Status: 🔴 P0 - Cross-user profile access

 ─────────────────────────────────────────────────────────
 IDOR Testing
 ─────────────────────────────────────────────────────────

 Test: Access other user's orders by ID
 ├── Request: GET /orders?user_id=eq.[other-user-id]
 ├── Auth: Test user JWT
 ├── Response: 200 OK - 15 orders returned
 └── Status: 🔴 P0 - IDOR VULNERABILITY

 Proof:
 curl "$URL/rest/v1/orders?user_id=eq.other-user-uuid" \
   -H "Authorization: Bearer [test-user-jwt]"
 # Returns orders belonging to other-user-uuid!

 Test: Access admin endpoints
 ├── Request: GET /functions/v1/admin-panel
 ├── Auth: Test user JWT (regular user)
 ├── Response: 200 OK - Admin data returned!
 └── Status: 🔴 P0 - PRIVILEGE ESCALATION

 ─────────────────────────────────────────────────────────
 Storage with Authentication
 ─────────────────────────────────────────────────────────

 Bucket: documents
 ├── Anonymous: ❌ 0 files (blocked)
 ├── Authenticated: ✅ 523 files visible ← ALL USERS' FILES!
 └── Status: 🔴 P1 - Auth users see all documents

 Bucket: user-uploads
 ├── Anonymous: ❌ 0 files
 ├── Authenticated: 3 files (own files only)
 └── Status: ✅ RLS working correctly

 ─────────────────────────────────────────────────────────
 Summary
 ─────────────────────────────────────────────────────────

 New Findings (Auth-only):
 ├── 🔴 P0: users table - all users visible to any auth user
 ├── 🔴 P0: profiles table - cross-user access
 ├── 🔴 P0: IDOR in orders - can access any user's orders
 ├── 🔴 P0: Privilege escalation in admin-panel
 └── 🟠 P1: documents bucket - all files visible to auth users

 Comparison:
 ├── Issues found (Anonymous): 3
 ├── Issues found (Authenticated): 8 ← 5 NEW ISSUES!
 └── Auth-only vulnerabilities: 5

 Recommendation:
 These issues were NOT visible in anonymous testing!
 Always test with authenticated users.

 ─────────────────────────────────────────────────────────
 Cleanup
 ─────────────────────────────────────────────────────────

 ⚠️  Test user still exists in database.

-- This RLS policy is correct
CREATE POLICY "Users see own data"
  ON users FOR SELECT
  USING (auth.uid() = id);

-- Result:
-- Anonymous: 0 rows
-- Authenticated: 1 row (own data)

-- This RLS policy is WRONG
CREATE POLICY "Authenticated users see all"
  ON users FOR SELECT
  USING (auth.role() = 'authenticated');  -- ❌ Too permissive!

-- Result:
-- Anonymous: 0 rows
-- Authenticated: ALL rows ← VULNERABILITY!

-- Fix: Add user ownership check
CREATE POLICY "Users see own data"
  ON users FOR SELECT
  USING (auth.uid() = id);  -- ✅ Only own row
