Echo: piscina: security update to 4.9.4

critical Tenable Cloud Security Plugin ID 472277

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - piscina is a node.js worker pool implementation. Prior to 4.9.4, 5.3.2, and 6.0.0-rc.5, Piscina stores
 ThreadPool.options in src/index.ts as a plain object that inherits from Object.prototype. Applications
 with a separate prototype-pollution primitive can therefore supply inherited values for security-sensitive
 options that do not have own defaults. An inherited execArgv value is passed to the Node.js Worker
 constructor and can preload attacker-controlled code in worker threads, an inherited loadBalancer function
 can execute during task scheduling, and inherited env values can alter worker environments. This issue is
 fixed in versions 4.9.4, 5.3.2, and 6.0.0-rc.5. (CVE-2026-102992)

Solution

Update the piscina library and its related packages to version 4.9.4 or later.
