MEDIUM

Why flagged The package downloads a prebuilt binary .deb (an Electron/Chromium-based application) from home-store-packages.uniontech.com, which is the UOS (UnionTech OS / Deepin) official app store repository — a Chinese Linux distribution's package mirror, not a random personal host. This is roughly analogous to pulling a .deb from a vendor's official distribution channel. However, it is still a non-Arch, non-upstream binary blob: a full Electron app with bundled Chromium that runs with user privileges, sourced from a third-party Chinese app store infrastructure. There is a sha512sum provided, which pins the specific artifact. The concern is real but moderate: if uniontech's app store infrastructure were compromised or the package swapped before the hash was recorded, arbitrary code would execute. The hash mitigates substitution attacks post-publication. The host (uniontech.com) is the official UOS vendor, not a personal or unknown host, which reduces but does not eliminate supply-chain risk. Overall this fits the medium category: a prebuilt executed binary from a non-standard (non-upstream, non-Arch) host with a checksum but no GPG signature verification.

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, …).
