MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from flavio.tordini.org, which is the upstream developer's own personal/official domain (the same domain listed as the package URL). This is a common pattern for closed-source proprietary software distributed by the developer. However, the binary is not open-source, is not from a major distribution mirror, and there is no GPG signature verification — only a sha256sum. The sha256sum provides integrity against accidental corruption but not against a targeted substitution attack on the upstream host. Since this is a closed-source prebuilt binary executed on the user's system, sourced from a personal domain without cryptographic signing, the supply-chain risk is real but not elevated beyond a typical 'binary from upstream developer' scenario. The risk is genuine (medium) but not malicious.

Triggered rules

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, …).
