Output:
【漏洞类型】信息泄露漏洞
【严重性】Medium
【漏洞摘要】原始代码中存在信息泄露漏洞，具体表现为在`getNoneCameraUploadTaskInfos`方法中未对`isCopyToLocal`标志进行正确处理，导致摄像头照片的上传任务信息（`UploadTaskInfo`）被错误地包含在返回的列表中。这可能会泄露用户的隐私，尤其是当这些信息被广播或记录时。根本原因是开发人员在注释掉的条件检查中引入了错误的逻辑，即没有正确区分摄像头照片上传任务和其他文件上传任务。
【关键代码模式】`UploadTaskInfo.isCopyToLocal`、`getNoneCameraUploadTaskInfos`、`notifyProgress`。
【修复方法说明】修复方法通过重新启用对`isCopyToLocal`标志的检查，确保只有非摄像头照片的上传任务信息被包含在返回的列表中，防止了隐私泄露。

Output:
【漏洞类型】跨站脚本攻击（XSS）
【严重性】高
【漏洞摘要】原始代码中存在XSS漏洞，主要问题出在`UserStatePreloader`类的`getStateJson`方法中。该方法将用户数据序列化为JSON格式，并通过`header.jelly`文件输出到HTML页面中。由于用户数据可能包含恶意脚本，而`JSONDataWriter`类在序列化字符串时没有进行HTML编码，攻击者可以通过构造恶意输入来注入恶意脚本，从而在用户浏览器中执行任意JavaScript代码。
【关键代码模式】关键代码模式包括：
- `UserStatePreloader.java`中的`getStateJson`方法，负责将用户数据序列化为JSON格式并输出。
- `header.jelly`文件，负责将序列化后的JSON数据嵌入到HTML页面中。
- `JSONDataWriter.java`中的`value`方法，负责序列化字符串值。
【修复方法说明】修复方法在`Export`类和`ExportConfig`类中添加了`withHtmlEncode`方法和`htmlEncode`字段，以支持HTML编码。在`UserStatePreloader`类中将`htmlEncode`参数设置为`true`，确保输出的JSON数据被HTML编码，从而防止恶意脚本的注入和执行。
