LOW

Why flagged Prebuilt binaries downloaded directly from UCSC's official bioinformatics download server (hgdownload.soe.ucsc.edu), which is the project's own infrastructure, with sha256 checksums provided for all files; the host is non-standard but is the legitimate upstream source for UCSC tools, making this a normal prebuilt-binary packaging with no obfuscation or exfiltration concerns.

Triggered rules

LOW Few votes, recently uploaded zero_votes_recent

Uploaded within the last 14 days with 2 or fewer community votes — little peer review so far.

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-sonnet-4.6) reviewed the full PKGBUILD and judged it LOW (confidence 80%): Prebuilt binaries downloaded directly from UCSC's official bioinformatics download server (hgdownload.soe.ucsc.edu), which is the project's own infrastructure, with sha256 checksums provided for all files; the host is non-standard but is the legitimate upstream source for UCSC tools, making this a normal prebuilt-binary packaging with no obfuscation or exfiltration concerns.

1 higher static finding superseded - not the current verdict (shown for transparency)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