Why flagged

The PKGBUILD downloads a prebuilt x86_64 binary (.deb) directly from tonelib.net, the vendor's own website, and installs it. This is a common AUR pattern for proprietary software distributed as .deb packages (similar to many -bin packages). The sha256sum is pinned, which mitigates casual tampering, but the source URL points to a floating/unversioned path (ToneLib-NoiseReducer-amd64.deb) rather than a versioned artifact — meaning the checksum would catch a swap only if the file changes and the PKGBUILD is updated accordingly. The real concern is that tonelib.net is a small vendor host with no transparency (no GitHub releases, no signed packages), so a compromise of that host or a silent file replacement would deliver arbitrary code to users. This is a genuine supply-chain concern for an executed binary from a non-standard host, consistent with MEDIUM severity. There is no obfuscation, no piracy, and the package appears functional.

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, …).
