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.

Nezha Monitering是Nezha Monitoring组织开源的一款自托管、轻量级的服务器和网站监控及运维工具。 nezhahq nezha monitoring 0.20.0版本至2.0.10之前版本存在服务端请求伪造漏洞，该漏洞源于可配置任意webhook_url、HTTP方法、请求体和标头，且未使用SSRF保护，可能导致低权限认证用户通过控制服务器或DDNS配置文件使仪表盘主机向回环或内部网络服务发起HTTP请求，形成盲SSRF或内部状态更改请求基元。

Vulnerability Title
Nezha Monitoring: Authenticated DDNS webhook configuration allows blind SSRF from the dashboard host
Source: CVE Program / CVE List V5
Vulnerability Description
Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From version 0.20.0 to before version 2.0.10, an authenticated Nezha dashboard user can create or update a DDNS profile with provider webhook and configure an arbitrary webhook_url, HTTP method, request body, and headers. When DDNS is triggered for a server that uses that profile, the dashboard process sends the configured request with utils.HttpClient without the SSRF protections used by notification webhooks. This allows a low-privileged authenticated user who controls an owned server/DDNS profile to make the dashboard host issue HTTP requests to loopback or internal network services. The response body is not returned to the attacker in the confirmed path, so this is a blind SSRF / internal state-changing request primitive. This issue has been patched in version 2.0.10.
