Why flagged

The PKGBUILD downloads a prebuilt AppImage binary from download.audius.co (the official Audius download domain) and executes it during prepare() via --appimage-extract to unpack it. The domain appears to be the legitimate official distribution host for Audius desktop releases. However, sha256sums=('SKIP') means there is no integrity verification of the downloaded binary, so any MITM or server-side substitution would go undetected. Executing an unverified binary during the build process is a genuine supply-chain concern. The source host itself is plausibly official, but the lack of checksum verification elevates this above 'low'. This is a real but non-malicious medium-risk pattern: an executed binary from what appears to be the official host, but with no integrity check.

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, …).
