Researchers Demonstrate Node2Shell RCE Exploit on Node.js Build Using Crafted Brotli Data
// summary
Researchers demonstrated a Node.js remote code execution proof of concept using crafted Brotli data processed by the bundled decoder, affecting an official Linux arm64 Node.js 24.22.0 image.

Malicious Brotli data can make an application on an official build of Node.js run attacker-supplied code, security researchers at Imperva have demonstrated. Their "Node2Shell" proof of concept ran code on the official Node.js 24.22.0 image for Linux arm64, with no debugger or custom build, by feeding crafted data to the bundled Brotli decoder (CVE-2026-111497). Node.js disclosed the flaw
