Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Uptime Kuma是Louis Lam个人开发者的一个易于使用的自托管监控工具。 Uptime Kuma 1.22.1之前版本存在路径遍历漏洞，该漏洞源于允许经过身份验证的用户从官方插件列表中安装插件，由于插件未根据官方插件列表进行验证或清理，因此很容易出现路径遍历。

Vulnerability Title
Uptime Kuma authenticated path traversal via plugin repository name may lead to unavailability or data loss
Source: CVE Program / CVE List V5
Vulnerability Description
Uptime Kuma, a self-hosted monitoring tool, has a path traversal vulnerability in versions prior to 1.22.1. Uptime Kuma allows authenticated users to install plugins from an official list of plugins. This feature is currently disabled in the web interface, but the corresponding API endpoints are still available after login. Before a plugin is downloaded, the plugin installation directory is checked for existence. If it exists, it's removed before the plugin installation. Because the plugin is not validated against the official list of plugins or sanitized, the check for existence and the removal of the plugin installation directory are prone to path traversal. This vulnerability allows an authenticated attacker to delete files from the server Uptime Kuma is running on. Depending on which files are deleted, Uptime Kuma or the whole system may become unavailable due to data loss.
