Why flagged

The PKGBUILD downloads a prebuilt binary .deb from packagecloud.io (a legitimate third-party package hosting service used by many open-source projects including fd.io/VPP for their official releases). The SHA256 checksum is pinned, which mitigates substitution attacks. However, the concern is real: this is a prebuilt binary extracted and installed directly, sourced from a CDN/hosting service rather than built from source. packagecloud.io is a legitimate hosting platform and fd.io does officially publish VPP packages there, so this is not an unofficial or personal host — it is the project's official distribution channel for Ubuntu packages. The risk is lower than a truly unofficial host, but installing prebuilt binaries (shared libraries from libvppinfra) that will be loaded into processes is a genuine supply-chain concern if the upstream host or account were ever compromised. The pinned checksum provides meaningful protection. Overall this sits at the lower end of medium: it's a prebuilt binary from an official but indirect distribution channel with a checksum, not clearly malicious but not source-built either.

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, …).
