View on AUR

Why flagged

The PKGBUILD downloads a prebuilt binary .deb from d.zhumu.com, which is the official CDN/download host for Zhumu (a Chinese Zoom-based video conferencing service, zhumu.me). The domain is consistent with the vendor's own infrastructure. However, the source URL uses HTTP (not HTTPS), meaning the download is not transport-encrypted and could be intercepted or tampered with in transit. The sha256sum provides integrity verification after download, which mitigates MITM to some degree, but the lack of TLS is still a concern. The package extracts and installs a prebuilt proprietary binary directly, which is the standard pattern for closed-source software AUR packages. The risk is real but typical for this class of package: a prebuilt binary from a vendor CDN over plain HTTP. Medium is appropriate.

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, …).
