MEDIUM

Why flagged The PKGBUILD downloads prebuilt proprietary binaries (KISSlicer) directly from kisslicer.com and installs them as executable files. This is the official vendor website for KISSlicer, not a personal or unofficial host, so the source is as legitimate as it can be for a closed-source binary. However, the download uses plain HTTP (not HTTPS), meaning the binary could be intercepted and replaced in transit (MITM attack), and the checksums only protect against accidental corruption or a compromised server — they do not protect against a MITM on an unencrypted channel. The binary itself is a closed-source executable installed to /opt and /usr/bin with no source code available for inspection. This is a classic AUR prebuilt-binary pattern: the risk is real (executed binary from a non-auditable source over plain HTTP) but not clearly malicious. Medium is the correct rating.

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
