MEDIUM

Why flagged The package downloads a prebuilt binary .deb (an Electron/Chromium-based desktop application) from home-store-packages.uniontech.com, which is the UOS (UnionTech OS / Deepin) app store package mirror — a Chinese Linux distribution's official app store infrastructure, not the upstream vendor's (mastergo.com) own distribution channel. While uniontech.com is a real company (makers of Deepin/UOS Linux), this is still a third-party redistributor rather than the upstream software vendor's own release host. The extracted binary is directly executed (master-desktop is symlinked into /usr/bin), so any tampering or compromise of that host would result in arbitrary code execution. The sha512sum is present and pinned, which mitigates interception risk but not a compromised upstream host. This is a genuine medium-severity supply-chain concern: a prebuilt, closed-source, executed binary from a third-party redistribution host rather than the software author's official release channel.

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, …).
