Why flagged

This PKGBUILD downloads a prebuilt binary package (.pkg.tar.zst) from x11libre.net, which is a third-party host not affiliated with the official Arch Linux or X.Org infrastructure. The binary is then extracted and installed directly into the package directory. While a sha256sum is provided (offering some integrity protection against transit tampering), the trust anchor is entirely the x11libre.net domain — if that domain is compromised or the maintainer is malicious, arbitrary binaries could be executed on the user's system. XLibre is a real X.Org fork project, but distributing prebuilt binaries from a personal/project website rather than building from source is a genuine supply-chain concern: there is no way to verify the binary matches any published source code, and the build is not reproducible. This is a classic medium-severity pattern: executed binary from an unofficial/personal host with no source build.

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, …).
