CVE-2026-55849: @cyclonedx/cyclonedx-npm: Shell Injection via Unsanitized --workspace Argument

June 19, 2026

A command injection vulnerability exists in @cyclonedx/cyclonedx-npm when the CLI is invoked with the --workspace <value> option while the environment variable npm_execpath is unset or empty. User‑supplied --workspace values are passed to a subshell without proper sanitization, enabling attackers to inject arbitrary OS commands. This issue corresponds to CWE‑78: Improper Neutralization of Special Elements used in an OS Command.

The vulnerability was fixed in version [5.0.0][v5.0.0].
