Command Injection in CycloneDX npm CLI

Publication date: 2026-07-08

Last updated on: 2026-07-08

Assigner: GitHub, Inc.

Description
@cyclonedx/cyclonedx-npm creates CycloneDX Software Bill of Materials from npm projects. From 2.1.0 before 5.0.0, the CLI passes user-supplied --workspace values to a subshell without proper sanitization when npm_execpath is unset or empty, allowing arbitrary OS command execution with the privileges of the invoking user. This issue is fixed in version 5.0.0.

Executive Summary

The vulnerability exists in the @cyclonedx/cyclonedx-npm package versions from 2.1.0 up to but not including 5.0.0. The command line interface (CLI) passes user-supplied --workspace values to a subshell without properly sanitizing them when the npm_execpath environment variable is unset or empty. This improper sanitization allows an attacker to execute arbitrary operating system commands with the privileges of the user running the CLI.

The issue is resolved in version 5.0.0 of the package.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary OS commands with the same privileges as the user invoking the CLI. This could lead to unauthorized actions such as data theft, modification, deletion, or further compromise of the system depending on the user's permissions.

Mitigation Strategies

To mitigate this vulnerability, upgrade @cyclonedx/cyclonedx-npm to version 5.0.0 or later, where the issue is fixed.
