### 历史更新记录
|
||||
|
||||
#### > 2026年10月08日，v5.0.3 安全补丁版本发布：
|
||||
|
||||
#### 安全修复
|
||||
1. FTP 连接前校验命令参数，阻止控制字符注入
|
||||
2. 上传和建目录限制在演示文件目录内，并检查符号链接
|
||||
3. 校验所有预览源地址，阻止通过不同参数绕过信任策略
|
||||
4. 预览页码和代理参数经过类型校验后再渲染模板
|
||||
5. 在通过校验的压缩包预览中生成目录树，移除公开的 `/directory` 接口
|
||||
6. 默认仅开放汇总健康状态，不再默认暴露健康详情、info 和 metrics
|
||||
|
||||
#### 升级说明
|
||||
1. 建议所有 v5.0.2 及更早版本用户升级至 v5.0.3，继续要求 JDK 21 及以上
|
||||
2. 已有外部配置文件需设置 `management.endpoints.web.exposure.include=health` 和 `management.endpoint.health.show-details=never`，才能应用监控配置加固
|
||||
3. `/directory` 接口已移除，内置压缩包目录预览继续可用
|
||||
4. 上传仍默认禁用；启用后，上传和建目录仅允许演示目录内的路径

## Change History
|
||||
|
||||
### Version 5.0.3 (October 8, 2026)
|
||||
|
||||
#### Security Fixes
|
||||
1. Reject control characters in FTP command arguments before connecting
|
||||
2. Confine uploads and folder creation to demo storage, including symbolic-link checks
|
||||
3. Validate every preview source URL to prevent parameter-confusion bypasses of trust policies
|
||||
4. Validate page and agent parameters before rendering preview templates
|
||||
5. Render archive directory trees within the validated preview flow and remove the public `/directory` endpoint
|
||||
6. Expose only aggregate health status by default; detailed health, info, and metrics are no longer public defaults
|
||||
|
||||
#### Upgrade Notes
|
||||
1. All v5.0.2 and earlier users should upgrade to v5.0.3; JDK 21 or higher remains required
|
||||
2. Existing external configuration files must set `management.endpoints.web.exposure.include=health` and `management.endpoint.health.show-details=never` to apply the monitoring hardening
|
||||
3. The `/directory` endpoint is removed; the built-in archive preview remains supported
|
||||
4. Uploads remain disabled by default. Enabled uploads and folder creation accept only paths beneath demo storage
|
||||
|
||||
### Version 5.0.2 (August 14, 2026)
|
||||
|
||||
