SCA: security update for github.com/nezhahq/nezha (GHSA-jg62-j5h6-8mpq)

medium Tenable Self-Hosted Container Security Plugin ID 444041

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 1.0.0 to before version 2.2.0, the Nezha dashboard exposes two endpoints that create long-lived
 WebSocket streams to monitored agents: POST /api/v1/terminal → createTerminal() (terminal.go:27-67) and
 POST /api/v1/file → createFM() (fm.go:28-67). Both call rpc.NezhaHandlerSingleton.CreateStream(streamId,
 ...) which inserts a new ioStreamContext into an unbounded map[string]*ioStreamContext (s.ioStreams in
 io_stream.go:59-67). There is no per-user rate limit, no global semaphore, and no per-server connection
 cap. This issue has been patched in version 2.2.0. (CVE-2026-53522)

Solution

Update the github.com/nezhahq/nezha library and its related packages to version 2.2.0 or later.
