CVE-2026-110639: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in mborne @mborne/extract
Description
@mborne/extract before 0.2.1 contains an OS command injection vulnerability that allows attackers to execute commands by supplying shell metacharacters in archivePath or targetDir options. Attackers controlling these values passed to extract() can inject commands into unquoted shelljs exec() strings in the unzip, 7z, tar-bz2 and gz extractors, running them with Node.js process privileges.

Technical Analysis
CVE-2026-110639 is an OS command injection vulnerability in the @mborne/extract Node.js package prior to version 0.2.1. The vulnerability arises because user-controlled inputs (archivePath or targetDir) are passed unquoted to shelljs exec() commands within multiple archive extractors (unzip, 7z, tar-bz2, gz). This improper neutralization of special shell characters allows attackers to inject and execute arbitrary OS commands with Node.js process privileges.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary OS commands on the host system with the privileges of the Node.js process running @mborne/extract. This can lead to full system compromise depending on the process privileges. The vulnerability is critical due to its remote network attack vector, no required privileges, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade @mborne/extract to version 0.2.1 or later, where this OS command injection vulnerability is fixed. Until then, avoid passing untrusted input to the archivePath or targetDir options. No official patch link was provided, but the version 0.2.1 release addresses this issue.
