GHSA-85C8-PPGW-CCPR Tinypool: Prototype Pollution Gadget to RCE in run() options

tinypool is a fork of piscina and inherited the same prototype-pollution surface. When pool.runtask, options is called, the filename option is read from the provided options object. If that object does not have an own filename property, the lookup falls through to Object.prototype. An attacker wh...

CVE-2026-104848

Tinypool is a minimal Node.js worker thread pool implementation. Prior to 2.1.1, Tinypool constructs ThreadPool.options from a normal options object and reads the execArgv and env worker options in dist/index.js, allowing values inherited from a polluted Object.prototype to be copied into own...

CVE-2026-104849

Tinypool is a minimal Node.js worker thread pool implementation. Prior to 2.1.2, Tinypool reads filename from a caller-supplied options object in pool.runtask, options without requiring an own property, so a polluted Object.prototype.filename can replace the intended worker module. Applications a...

CVE-2026-104849

The Tinypool Node.js worker thread pool implementation (prior to version 2.1.2 ) is vulnerable to a prototype pollution gadget. The issue arises because pool.run(task, options) reads the filename property from a caller-supplied options object without requiring an own property . If an attacker pol...

CVE-2026-104848

The Tinypool minimal Node.js worker thread pool implementation is vulnerable to a Prototype Pollution gadget in versions prior to 2.1.1 . The root cause is located in dist/index.js, where the software constructs ThreadPool.options from a normal options object and reads execArgv and env worker opt...
