MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from tonelib.net (the vendor's own website) and installs its contents directly. This is the official vendor site for ToneLib products, so it is not a random personal host. However, the source URL is not versioned/pinned — it points to a floating 'latest' URL (ToneLib-Zoom-amd64.deb with no version in the filename), meaning the sha256sum provides integrity only at the time of packaging; any future update to that URL would break the checksum rather than silently deliver malicious code. The real concern is that a prebuilt closed-source binary is being extracted and installed system-wide, and the source is a proprietary vendor's download server rather than a reproducible build. This is a legitimate medium supply-chain concern (executed binary from a non-distro host with a floating URL), but not an active attack. The sha256sum does provide some protection against interception at the pinned version.

An AI model (anthropic/claude-4.6-sonnet-20260217) reviewed this and agrees it is MEDIUM (confidence 72%): The PKGBUILD downloads a prebuilt binary .deb from tonelib.net (the vendor's own website) and installs its contents directly.
