The README advertises that binaries come from GitHub Releases at `github.com/yongjie0203/veteran/releases`, but the install script hardcodes `your-website.com` with a Chinese-language comment instructing the maintainer to replace it with their real download host — the package was published to npm with the placeholder in place. There is no hash or signature verification of the fetched bytes. Whoever registers or already controls `your-website.com` can ship arbitrary executables to every installer of this package, with full code execution on the installer's machine.
