SCA: security update for github.com/nezhahq/nezha (GHSA-6x26-5727-rrm9)

medium Tenable Cloud Security Plugin ID 442548

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-47268)

Solution

Update the github.com/nezhahq/nezha library and its related packages to version 2.0.10 or later.
