Why flagged

This PKGBUILD downloads a prebuilt binary package (.pkg.tar.zst) from x11libre.net, which is not an official Arch Linux mirror or a well-known upstream vendor host. XLibre is a fork of X.Org, and x11libre.net appears to be its project site, but it is not a widely recognized or audited distribution channel. The package extracts and installs the binary directly into pkgdir without any source build, meaning users are trusting a third-party binary entirely. A sha256sum is provided, which mitigates tampering in transit but does not address the trustworthiness of the host itself. The binary is an X input driver (xf86-input-wacom replacement) that runs with X server privileges, so a compromised or malicious binary would have significant impact. This is a genuine supply-chain concern: an unofficial host serving executed binaries that replace a core X.Org component, even if the project appears legitimate. The medium rating is appropriate.

Triggered rules
