MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from alilang.alibaba-inc.com, which is the official Alibaba intranet client portal. The domain is Alibaba's own infrastructure (alibaba-inc.com), so this is not a random personal host — it is the vendor's own distribution endpoint. However, the package installs a closed-source, prebuilt binary that runs as root (via gksu), is linked into /etc/init.d as a service, and has no integrity verification beyond a single MD5 checksum (which is cryptographically weak). The binary is executed directly on the user's system with elevated privileges. The combination of: (1) a prebuilt proprietary binary, (2) weak integrity check only (MD5, no GPG), (3) root execution via gksu, and (4) installation as an init.d service constitutes a genuine supply-chain risk — if the upstream URL were ever compromised or the file silently replaced, the MD5 would not provide meaningful protection. This meets the medium threshold: an executed binary from a host that, while plausibly official, is not independently verifiable and lacks strong integrity guarantees.

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