CVE-2023-26128Public exploit

Command execution via unsanitized module name

Published May 27, 2023 · Updated Jan 13, 2025

OS command injection in keep-module-latest 1.0.1 and earlier allows local users to execute commands through a crafted module name. The installModule function interpolates moduleName and registry directly into an npm install command passed to child_process.execSync without escaping. Reachability requires the ability to run Node.js code that calls the package with attacker-controlled options, and injected shell metacharacters execute with the hosting process's permissions.
