Why flagged

The package builds from a source tarball hosted on the project's own plausible domain, and the additional wget in prepare() only downloads static documentation (HTML/images), which cannot execute code; both flagged URLs are from the same legitimate project host.

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 builds from a source tarball hosted on the project's own plausible domain, and the additional wget in prepare() only downloads static documentation (HTML/images), which cannot execute code; both flagged URLs are from the same legitimate project host.

2 higher static findings superseded - not the current verdict (shown for transparency)

Medium External download from an untrusted host, not in source=() external_download_not_in_source

curl/wget fetches a URL on a non-allowlisted host that is not part of source=(), so it is not checksum-verified by makepkg.

PKGBUILD:30 wget -P $srcdir/undither-doc -r -nH -nd -np -nc -k -A html,gif,jpg "http://www.madingley.org/james/resources/undither/"

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, …).
