Why flagged

The PKGBUILD downloads a prebuilt binary .deb from a non-standard host (office.hecmcc.com) on an unusual port (9003), which is not the project's official release infrastructure (cmccsi.cn). The binary is extracted and installed directly into the package root (opt/ and usr/), meaning arbitrary executables from this third-party host run with user privileges. While the sha256sum provides some integrity check, the host is not an official vendor mirror and could be a personal or unofficial server. This is a genuine supply-chain concern: if the host is compromised or the binary is replaced, users would execute malicious code. The package is not clearly malicious, but the combination of a prebuilt binary from an unofficial host on a non-standard port warrants a medium rating.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
