# Security Test Results - IDOR Protection Complete
**Date:** 2025-12-31
**Focus:** Profile Data Export IDOR Protection + Cross-Guard Security
**Test Database:** timebank_cc_2 (development database with real data)

---

## Executive Summary

**STATUS: ✅ ALL TESTS PASSING (100%)**

All 5 profile data export methods are now fully protected against IDOR (Insecure Direct Object Reference) vulnerabilities with comprehensive test coverage across all profile types (User, Organization, Bank).

**Critical Security Fix:** Added cross-guard attack prevention to ProfileAuthorizationHelper, blocking unauthorized access when users attempt to access profiles on different authentication guards.

## Security Improvements Implemented

### 1. ProfileAuthorizationHelper Enhancement
**File:** `app/Helpers/ProfileAuthorizationHelper.php`
**Lines:** 63-101

**NEW: Cross-Guard Attack Prevention**
```php
// IMPORTANT: Verify guard matches profile type to prevent cross-guard attacks
// Even if the user has a relationship with the profile, they must be
// authenticated on the correct guard

Expected guard mapping:
- Bank profiles → require 'bank' guard authentication
- Organization profiles → require 'organization' guard authentication
- Admin profiles → require 'admin' guard authentication
- User profiles → require 'web' guard authentication
```

**Protection Logic:**
1. Determines expected guard for target profile type
2. Checks which guard current authentication is from
3. Blocks access if guards don't match
4. Logs cross-guard attempts for security monitoring

**Example Attack Blocked:**
- User authenticated on 'web' guard
- User IS a manager of Bank ID 1 (valid database relationship)
- User manipulates session: `activeProfileType = Bank, activeProfileId = 1`
- **OLD BEHAVIOR:** Access granted (database relationship exists)
- **NEW BEHAVIOR:** 403 Forbidden (wrong guard) + logged warning

### 2. ExportProfileData Protection
**File:** `app/Http/Livewire/Profile/ExportProfileData.php`

**All 5 export methods now protected:**

```php
public function exportTransactions($type)  // Line 45
public function exportProfileData($type)   // Line 147
public function exportMessages($type)      // Line 283
public function exportTags($type)          // Line 374
public function exportContacts($type)      // Line 441
```

**Authorization Flow (Applied to all methods):**
1. Get active profile from session
2. **Validate profile exists**
3. **ProfileAuthorizationHelper::authorize($profile)** ← CRITICAL
4. Validate export format
5. Perform export operation

**Key Improvement:** Authorization check happens BEFORE format validation and export operations, ensuring no data exposure on failed authorization.

## Attack Scenarios Tested & Blocked

### Session Manipulation Attacks ✅
**Attack:** User modifies session variables to access another user's data
```php
session(['activeProfileType' => User::class, 'activeProfileId' => $victim_id]);
```
**Protection:** ProfileAuthorizationHelper validates database ownership
**Result:** 403 Forbidden + logged warning

### Cross-Profile Attacks ✅
**Attack:** Organization 1 manipulates session to access Organization 2's data
```php
// Authenticated as Organization 1
session(['activeProfileType' => Organization::class, 'activeProfileId' => 2]);
```
**Protection:** Database relationship validation (user must be member of organization)
**Result:** 403 Forbidden

### Cross-Guard Attacks ✅ (NEW)
**Attack:** User on 'web' guard attempts to access Bank profile (even if they're a manager)
```php
$this->actingAs($user, 'web');  // Authenticated on web guard
session(['activeProfileType' => Bank::class, 'activeProfileId' => 1]);
```
**Protection:** Guard matching validation
**Result:** 403 Forbidden + "Cross-guard access attempt blocked" log

### Unauthenticated Access ✅
**Attack:** No authentication but session manipulation
```php
// No actingAs() call
session(['activeProfileType' => User::class, 'activeProfileId' => 1]);
```
**Protection:** Authentication check before authorization
**Result:** 401 Unauthorized
