MEDIUM

Why flagged The PKGBUILD downloads and executes a shell installer script (steuern.lu.2024nP.sh) from steuersoftware.lu.ch during the prepare() phase. The host appears to be the official Canton of Lucerne tax software distribution server (matching the official URL lu.ch domain), which is a legitimate Swiss cantonal government source. However, the checksum is set to SKIP, meaning any modification to the script — whether by the host being compromised or the file being silently updated — would go undetected. The script is executed with elevated trust during the build process, making this a real supply-chain concern: if the remote file is replaced with a malicious version, it would execute arbitrary code on the builder's machine. The domain is official-looking (lu.ch subdomain), but SKIP on an executed script is a genuine medium-severity issue regardless of source legitimacy.

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, …).
