CVE-2026-55849: Cyclonedx Cyclonedx-Node-Npm

High severity, CVSS 8.5. EPSS: 0.2% chance of exploitation in the next 30 days.

@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.

Affected products

• Cyclonedx Cyclonedx-Node-Npm: from 2.1.0, before 5.0.0 (fixed in 5.0.0)
