MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary (KISSlicer Linux executable) from kisslicer.com, which is the official upstream vendor website for KISSlicer. The binary is installed directly as an executable. While kisslicer.com is the legitimate vendor host (not a personal or unofficial mirror), the package installs a closed-source prebuilt binary with no source build, which is a standard supply-chain concern: if the upstream host is compromised or the file is replaced, users would execute arbitrary code. The sha256sum pinning provides some mitigation. This is a real medium-severity concern (prebuilt binary from a third-party host installed as executable) but not a high-severity attack — it matches the classic AUR binary-repackaging pattern that warrants medium rating.
