LOW

Why flagged The package downloads a versioned zip and signature from the official project domain for a well-known lossless audio tool, installs prebuilt binaries and data, and uses a SKIP'd checksum only for the signature; the source host is the project's own official site, making supply-chain risk low despite non-whitelisted domain and skipped sig check.

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 a versioned zip and signature from the official project domain for a well-known lossless audio tool, installs prebuilt binaries and data, and uses a SKIP'd checksum only for the signature; the source host is the project's own official site, making supply-chain risk low despite non-whitelisted domain and skipped sig check.

2 higher static findings superseded - not the current verdict (shown for transparency)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:14 sha1sums=("$(curl -s http://www.losslessaudio.org/Downloads/A1C0/${pkgver//./}/Linux/OptimFROG_Linux_x64_${pkgver//./}.zip.sha1 | cut -d ' ' -f1)"

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, …).

PKGBUILD:13 source=("http://www.losslessaudio.org/Downloads/A1C0/${pkgver//./}/Linux/OptimFROG_Linux_x64_${pkgver//./}".zip{,.sig})
