MEDIUM

Why flagged The package downloads a prebuilt binary .deb from home-store-packages.uniontech.com, which is the Deepin/UOS app store CDN (uniontech.com is the company behind Deepin Linux). This is not the software vendor's own official host (boardmix.cn), but rather a third-party app store mirror. The installed content is an Electron/Chromium-based application binary that will be executed on the user's system. While uniontech.com is a known Chinese Linux distribution company and their app store is a legitimate distribution channel, it is not the upstream vendor's own release infrastructure, creating a supply-chain dependency on a third party. The sha512sum is present and pins the specific artifact, which mitigates (but does not eliminate) the risk of substitution. This is a genuine medium-risk pattern: prebuilt executed binaries from a non-upstream host, consistent with the original 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, …).
