MEDIUM

Why flagged The PKGBUILD downloads prebuilt .deb binaries (containing an Electron app.asar and unpacked resources) from dlydbg.cmzq-office.com, which is a subdomain of cmzq-office.com — the same domain as the official product URL (oa.cmzq-office.com). This suggests it is the vendor's own download server rather than a random third-party host. However, it is still not a well-known, widely-audited distribution channel (no GitHub releases, no official Linux distro mirror), and the binaries are executed code (Electron app.asar + unpacked native modules) installed directly into /usr/lib. The sha256sums are pinned, which mitigates silent substitution at rest, but does not protect against the vendor intentionally shipping malicious code or the subdomain being compromised and checksums not updated. The pattern is consistent with many AUR 'bin' packages for Chinese enterprise software distributed via vendor CDNs, which is a recognized but non-zero supply-chain risk. This is a genuine medium: executed binary/compiled code from a non-mainstream host with no independent verification path.

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, …).
