SCA: security update for github.com/nezhahq/nezha (GHSA-5c25-7vpj-9mqh)

critical Tenable Cloud Security Plugin ID 444034

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. Prior to
version 2.0.13, fallbackToFrontend in the dashboard's NoRoute handler treats any URL whose raw string
starts with /dashboard as an admin-frontend asset request. The check uses strings.HasPrefix, not a path-
segment match, so the input /dashboard../data/config.yaml is accepted; strings.TrimPrefix leaves
../data/config.yaml; and path.Join("admin-dist", "../data/config.yaml") normalizes to data/config.yaml —
which os.Stat finds and http.ServeFile returns. No authentication required. This issue has been patched in
version 2.0.13. (CVE-2026-53519)

Solution

Update the github.com/nezhahq/nezha library and its related packages to version 2.0.13 or later.
