CyberRota Analysis
AI-GeneratedPiscina, a Node.js worker pool implementation, is vulnerable to prototype pollution, allowing attackers to manipulate security-sensitive options through inherited values. This can lead to the execution of arbitrary code in worker threads and unauthorized alterations of worker environments. Organizations using affected versions should prioritize upgrading to versions 4.9.4, 5.3.2, or 6.0.0-rc.5 to mitigate this critical risk.

Original NVD Description
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.
