Why flagged

This PKGBUILD downloads a prebuilt binary package (.pkg.tar.zst) from x11libre.net, which is a third-party host not affiliated with Arch Linux official repositories or a well-known upstream vendor mirror. The binary is an X input driver (xf86-input-elographics) that will be installed into the system and loaded by the X server, meaning it executes with significant privilege. While XLibre is a known X.Org fork project and the SHA256 checksum is present, the host x11libre.net is not an established, widely-audited distribution channel. The package extracts and installs the binary directly without building from source, bypassing any reproducibility or audit trail. This is a classic supply-chain risk pattern: a prebuilt binary from a personal/project host that could be silently replaced. The sha256sum provides some protection against in-transit tampering but not against the host serving a malicious binary from the start. Rated MEDIUM: real supply-chain concern with an executed binary from an unofficial host, but no evidence of active malice.

Triggered rules
