Why flagged

The package downloads official Brother printer driver RPMs from brother.com, a legitimate vendor domain, for building a CUPS driver; the non-whitelisted host is part of Brother's official infrastructure, and the source is not executable code but vendor-provided drivers, making the risk low despite the static analysis flag.

Triggered rules

Low AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-07-25) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package downloads official Brother printer driver RPMs from brother.com, a legitimate vendor domain, for building a CUPS driver; the non-whitelisted host is part of Brother's official infrastructure, and the source is not executable code but vendor-provided drivers, making the risk low despite the static analysis flag.

1 higher static finding superseded - not the current verdict (shown for transparency)

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, …).
