SCA: security update for github.com/nezhahq/nezha (GHSA-99gv-2m7h-3hh9)

critical Tenable Cloud Security Plugin ID 442320

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, a RoleMember user can create a scheduled cron task with
 Cover=CronCoverAll, Servers=[] and an arbitrary Command. At every tick of the scheduler, the dashboard
 pushes that command to every server in the global ServerShared map — including servers that belong to
 other tenants (admin's servers, other members' servers). Each agent runs the command and returns the
 output, which is then sent to the attacker's own NotificationGroup → attacker-controlled webhook. This
 issue has been patched in version 2.0.8. (CVE-2026-46716)

Solution

Update the github.com/nezhahq/nezha library and its related packages to version 1.14.15-0.20260517022419-d7526351cf97 or later.
