Description@cyclonedx/cyclonedx-npm creates CycloneDX Software Bill of Materials from npm projects. Prior to version 6.0.0, the Windows fallback path in src/npmRunner.ts, used when npm_execpath does not provide the npm CLI path, can construct a shell command containing an untrusted value from the --workspace option. When an attacker can influence that option and the fallback npm execution path is reached, shell metacharacters in the workspace value can execute arbitrary operating-system commands with the privileges of the user running the CLI, allowing data access, file modification, or service disruption. This issue is fixed in version 6.0.0.
