MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary from tuf.werf.io, which is the official TUF (The Update Framework) distribution endpoint for the werf project (werf.io is the official project site). TUF is a security framework specifically designed for secure software distribution, so this is actually the official, security-hardened release channel rather than a random personal host. However, it is still a prebuilt binary being installed directly to /usr/bin without source compilation, and the host tuf.werf.io, while official, is not a widely recognized platform like GitHub releases. A sha256sum is provided. The medium rating is borderline — this is the official vendor distribution mechanism — but since it installs an unauditable prebuilt binary directly to the system, the supply-chain concern is real if the host were compromised, and the binary cannot be verified beyond the single checksum. This is a common AUR pattern for -bin packages from official vendor hosts, making it closer to clean/low, but the non-GitHub/non-standard host and direct binary execution keep it at medium.

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, …).
