MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from deepinos.org.cn (a Deepin OS app store mirror/CDN), not from the official freewb.org upstream. The binary contains an fcitx input method plugin (shared library) that is extracted and installed directly into /usr/lib/fcitx. There is a sha256 checksum, which mitigates substitution risk somewhat, but the source host is a third-party Chinese app store rather than the official project host. Since this is an executed/loaded binary (a shared library loaded by fcitx) from an unofficial host, the medium rating is appropriate — it's not clearly malicious but represents a genuine supply-chain concern.

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, …).
