用于从 npm 项目中生成 CycloneDX 软件物料清单（SBOM）。在 6.0.0 版本之前， 中的 Windows 回退路径（在 未能提供 npm CLI 路径时使用）可能会构造出包含来自 选项中不可信值的 shell 命令。当攻击者能够影响该选项值，且触发了回退的 npm 执行路径时，workspace 值中的 shell 元字符可能导致以运行 CLI 的用户权限执行任意操作系统命令，从而导致数据泄露、文件被修改或服务中断。该问题已在 6.0.0 版本中修复。

Vulnerability Title
@cyclonedx/cyclonedx-npm: Shell Injection via Unsanitized --workspace Argument on Windows
Source: CVE Program / CVE List V5
Vulnerability 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.
