### 2. Profile Deletion Authorization ❌ **CRITICAL FAILURES**

**Test Suite:** `ProfileDeletionAuthorizationTest`
**Status:** ❌ 4 of 7 tests FAILED
**Severity:** **CRITICAL**
**Date:** 2025-12-28

#### Test Results

| Test | Status | Severity |
|------|--------|----------|
| User cannot delete another user's profile | ❌ FAILED | **CRITICAL** |
| User cannot delete org they don't own | ❌ FAILED | **CRITICAL** |
| Central bank cannot be deleted | ❌ ERROR | HIGH |
| Final admin cannot be deleted | ✅ PASSED | - |
| User can delete own profile | ✅ PASSED | - |
| Wrong password prevents deletion | ✅ PASSED | - |
| Unauthenticated access blocked | ❌ ERROR | MEDIUM |

#### Critical Vulnerability Details

**VULNERABILITY 1: Cross-User Profile Deletion**

**Location:** `app/Http/Livewire/Profile/DeleteUserForm.php`
**Line:** 209-213

```php
// Get the active profile using helper
$profile = getActiveProfile();

if (!$profile) {
    throw new \Exception('No active profile found.');
}
```

**Issue:**
The `getActiveProfile()` helper trusts session data (`activeProfileId`) without validating that the authenticated user has permission to act as that profile.

**Attack Scenario:**
```php
// Attacker (user1) is logged in
Auth::user(); // Returns user1

// Attacker manipulates session
session(['activeProfileType' => 'App\\Models\\User']);
session(['activeProfileId' => 2]); // Target: user2's ID

// Calls DeleteUserForm::deleteUser()
// Result: user2's profile is DELETED
```

**Impact:**
- Any authenticated user can delete ANY other user's profile
- No validation of profile ownership
- Complete bypass of authorization
- Data loss and account takeover possible

---

**VULNERABILITY 2: Cross-Organization Profile Deletion**

**Location:** Same as Vulnerability 1
**Issue:** Same root cause - no ownership validation

**Attack Scenario:**
```php
// Attacker has access to org1
Auth::user()->organizations; // [org1]

// Attacker manipulates session
session(['activeProfileType' => 'App\\Models\\Organization']);
session(['activeProfileId' => 999]); // Target: org999 (not linked to attacker)

// Calls DeleteUserForm::deleteUser()
// Result: org999 is DELETED
```

**Impact:**
- User can delete organizations they're not linked to
- Bypass of organization membership validation
- Business accounts can be destroyed by unauthorized users

---

### Missing Authorization Checks

The `DeleteUserForm` component does NOT verify:

1. **User Profile:** That `auth()->user()->id === $profile->id`
2. **Organization Profile:** That `auth()->user()->organizations->contains($profile->id)`
3. **Bank Profile:** That `auth()->user()->banks->contains($profile->id)`
4. **Admin Profile:** That `auth()->user()->admins->contains($profile->id)`

---

## Other Test Findings

### 3. Email Routing Verification ⚠️ MEDIUM PRIORITY

**Audit Document:** `references/EMAIL_INTENDED_ROUTE_AUDIT.md`
**Status:** ⚠️ UX Issues Found

#### Issues Found
- ⚠️ 3 Inactive Profile Warning emails missing `intended` parameter
- ⚠️ 1 Profile Link Changed email missing `intended` parameter

**Impact:** Poor user experience (redirected to wrong page after email link click)
**Security Impact:** None
**Priority:** Medium (UX improvement)

---

### 4. Transaction Immutability Deployment Integration ✅ COMPLETED

**Script:** `scripts/test-transaction-immutability.sh`
**Integration:** `deploy.sh` lines 331-368
**Status:** ✅ Implemented and working

**Behavior:**
- Automatically runs after database migrations
- Stops deployment if immutability not enforced
- Provides clear remediation instructions

---

## Recommended Actions

### IMMEDIATE (Critical Priority)

1. **FIX PROFILE DELETION AUTHORIZATION**

   Add ownership validation to `DeleteUserForm.php` line ~210:

   ```php
   // Get the active profile using helper
   $profile = getActiveProfile();

   if (!$profile) {
       throw new \Exception('No active profile found.');
   }

   // CRITICAL: Validate user has permission for this profile
   $authenticatedUser = Auth::user();

   if ($profile instanceof \App\Models\User) {
       // User can only delete their own user profile
       if ($profile->id !== $authenticatedUser->id) {
           abort(403, 'Unauthorized: You cannot delete another user\'s profile.');
       }
   } elseif ($profile instanceof \App\Models\Organization) {
       // User must be linked to this organization
       if (!$authenticatedUser->organizations()->where('organizations.id', $profile->id)->exists()) {
           abort(403, 'Unauthorized: You are not linked to this organization.');
       }
   } elseif ($profile instanceof \App\Models\Bank) {
       // User must be linked to this bank
       if (!$authenticatedUser->banks()->where('banks.id', $profile->id)->exists()) {
           abort(403, 'Unauthorized: You are not linked to this bank.');
       }
   } elseif ($profile instanceof \App\Models\Admin) {
       // User must be linked to this admin profile
       if (!$authenticatedUser->admins()->where('admins.id', $profile->id)->exists()) {
           abort(403, 'Unauthorized: You are not linked to this admin profile.');
       }
   }
   ```

2. **CREATE GLOBAL AUTHORIZATION HELPER**

   Create `app/Helpers/ProfileAuthorizationHelper.php`:

   ```php
   <?php

   function validateProfileOwnership($profile)
   {
       $authenticatedUser = Auth::user();

       if (!$authenticatedUser) {
           throw new \Exception('User not authenticated');
       }

       if ($profile instanceof \App\Models\User) {
           if ($profile->id !== $authenticatedUser->id) {
               abort(403);
           }
       } elseif ($profile instanceof \App\Models\Organization) {
           if (!$authenticatedUser->organizations()->where('organizations.id', $profile->id)->exists()) {
               abort(403);
           }
       } elseif ($profile instanceof \App\Models\Bank) {
           if (!$authenticatedUser->banks()->where('banks.id', $profile->id)->exists()) {
               abort(403);
           }
       } elseif ($profile instanceof \App\Models\Admin) {
           if (!$authenticatedUser->admins()->where('admins.id', $profile->id)->exists()) {
               abort(403);
           }
       }

       return true;
   }
   ```

3. **ADD AUTHORIZATION TO ALL PROFILE-MODIFYING OPERATIONS**

   Audit and fix these components (estimated):
   - `Profile/UpdateProfileInformationForm.php`
   - `Profile/UpdateSettingsForm.php`
   - `Profile/UpdatePasswordForm.php`
   - `ProfileBank/UpdateProfileBankForm.php`
   - Any other profile edit/update/delete operations

4. **RUN FULL SECURITY TEST SUITE**

   After fixes:
   ```bash
   php artisan test --group=security --group=critical
   ```

### SHORT-TERM (High Priority)

1. **Fix email `intended` routing** (see EMAIL_INTENDED_ROUTE_AUDIT.md)
2. **Complete IDOR test suite** (currently has placeholders)
3. **Complete SQL injection test suite**
4. **Add middleware authorization checks**

### LONG-TERM (Medium Priority)

1. Implement formal Laravel Policies for all models
2. Add comprehensive audit logging for profile operations
3. Implement rate limiting on sensitive operations
4. Add IP-based access controls for admin operations

## Risk Assessment

### Critical Risks (Immediate Attention Required)

| Vulnerability | Severity | Exploitability | Impact | Status |
|--------------|----------|----------------|--------|--------|
| Profile deletion bypass | **CRITICAL** | **EASY** | **HIGH** | ❌ UNFIXED |
| Organization deletion bypass | **CRITICAL** | **EASY** | **HIGH** | ❌ UNFIXED |

**Exploitability: EASY**
- No special tools required
- Simple session manipulation via browser devtools
- No rate limiting on profile deletion
- No alerts/monitoring for suspicious activity

**Impact: HIGH**
- Complete account takeover possible
- Business data loss (organizations)
- User trust violation
- Potential legal/compliance issues

### Medium Risks

| Issue | Severity | Impact | Status |
|-------|----------|--------|--------|
| Email routing UX | MEDIUM | LOW | ⚠️ DOCUMENTED |
| Bank relationship validation | MEDIUM | MEDIUM | ⚠️ NEEDS TESTING |

---

## Compliance Impact

**GDPR/Data Protection:**
- Authorization bypass violates data protection requirements
- Unauthorized profile deletion = unauthorized data processing
- Potential fines and legal liability

**Financial Audit Requirements:**
- Transaction immutability: ✅ COMPLIANT (database level protection)
- Audit trail integrity: ⚠️ AT RISK (if admin accounts compromised)

---

## Next Steps

1. ⚠️ **URGENT:** Fix profile deletion authorization (today)
2. ⚠️ **URGENT:** Test fix with authorization test suite
3. ⚠️ **URGENT:** Audit all other profile-modifying operations
4. Deploy fixes to production with thorough testing
5. Continue with Phase 2 security testing
6. Implement monitoring for suspicious profile operations
