View on AUR

Why flagged

The package installs a prebuilt binary from a project-owned host with strong cross-checking via a release manifest, and the source is verified against a pinned checksum in the PKGBUILD; the untrusted host flags are mitigated by the integrity checks, making the risk low.

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-2507) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package installs a prebuilt binary from a project-owned host with strong cross-checking via a release manifest, and the source is verified against a pinned checksum in the PKGBUILD; the untrusted host flags are mitigated by the integrity checks, making the risk low.

2 higher static findings superseded - not the current verdict (shown for transparency)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:57 curl -fsSL "https://pkg.sober-dev.app/ce/SHA256SUMS?ref=${_upstream_version}" \

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, …).
