SCA: security update for github.com/nezhahq/nezha (GHSA-w4g9-mxgg-j532)

high Tenable Self-Hosted Container Security Plugin ID 442318

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 1.4.0 to before version 2.0.8, nezha's dashboard supports two user roles: RoleAdmin (Role==0) and
 RoleMember (Role==1). The notification routes POST /api/v1/notification and PATCH /api/v1/notification/:id
 are wired through commonHandler rather than adminHandler — so a RoleMember user can call them. These
 handlers synchronously Send() an HTTP request to a user-controlled URL and reflect the entire response
 body (no size limit) back to the caller on any non-2xx response. This issue has been patched in version
 2.0.8. (CVE-2026-46717)

Solution

Update the github.com/nezhahq/nezha library and its related packages to version 1.14.15-0.20260517022419-d06d539d34c1 or later.
