MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary .deb from rwork.crc.com.cn (the vendor's own domain for a Chinese enterprise collaboration app) and installs it directly. The host appears to be the official vendor site matching the package URL, so this is not a random personal host — it is the upstream distribution point. However, the package still installs an unverified prebuilt binary blob: only an MD5 checksum is used (cryptographically weak, no SHA256/b2), and there is no signature verification. The entire /opt tree from the .deb is copied into the system. If the vendor's download server were compromised or the MD5 collided, arbitrary code would execute with user privileges. This is a legitimate medium-risk supply-chain concern: a closed-source binary from a vendor host with only MD5 integrity checking, which is the standard AUR pattern for proprietary apps but still carries real risk compared to source-built packages.

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, …).
