Vulnerability Title
@cyclonedx/cyclonedx-npm: Shell Injection via Unsanitized `--workspace` Argument
Source: NVD (National Vulnerability Database)
Vulnerability 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.
