SCA: security update for github.com/nezhahq/nezha (GHSA-qjpp-gffx-2wm9)
medium Tenable Cloud Security Plugin ID 474705
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 2.2.7
until 2.2.11, ServiceSentinel.worker in service/singleton/servicesentinel.go checked an owned service
under servicesLock and later dereferenced pointer-valued serviceStatusToday and serviceCurrentStatusData
entries under serviceResponseDataStoreLock without revalidating that ServiceSentinel.Delete had not
removed them. A RoleMember could concurrently report TCP or ICMP results through the member's own agent
and delete the same owned service, causing a nil pointer dereference. Because the gRPC server had no
recovery interceptor, the worker panic terminated the whole dashboard process and disrupted every tenant's
web interface, REST API, and agent connections. The issue affects availability only and does not disclose
or modify data. This issue is fixed in versions 2.2.11 and 2.3.0. (CVE-2026-100394)
Solution
Update the github.com/nezhahq/nezha library and its related packages to version 0.0.0-20260721131105-c893aa57867d or later.See Also
