MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary archive (Phratch4.1-linux.zip) from phratch.com, which is the official project website for Phratch. The archive is unpacked and a binary ('phratch') is symlinked into /usr/bin, meaning the downloaded content is directly executed. There is a fixed md5sum checksum, which provides some integrity guarantee but MD5 is cryptographically weak. The host (phratch.com) is the upstream vendor's own domain, not a random personal host, which reduces but does not eliminate supply-chain risk. There are also minor issues: a duplicate 'source=' line (the first one referencing a local file that doesn't exist), and use of MD5 rather than SHA256. Overall this is a real medium-severity concern: a prebuilt executable from a small, unofficial project host with only MD5 verification, but not clearly malicious.

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, …).
