MEDIUM

Why flagged The PKGBUILD installs a prebuilt binary (tmpview) downloaded directly from style64.org, which is the upstream vendor's own website for this niche C64/assembly tool. The URL matches the package's declared upstream URL, so this is not a third-party or personal host — it is the official release host for this software. However, the binary is proprietary, pre-compiled, and not built from source, meaning users must trust the vendor's binary entirely. The sha512sum provides integrity verification against tampering in transit, but does not protect against a compromised upstream host serving a malicious binary. This is a classic 'binary blob from upstream vendor' scenario: legitimate but inherently carries supply-chain risk since no source build is possible. The cheaper model's concern about a 'non-standard host' is partially a false positive since style64.org is the actual upstream, but the risk of executing an unauditable proprietary binary is real enough to warrant medium rather than clean.

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, …).
