Why flagged

This PKGBUILD downloads a prebuilt x86_64 static binary directly from rebolsource.net (the official Rebol project host, but not a standard distribution channel like GitHub releases or a distro mirror) and installs it as an executable. The md5sums is set to 'SKIP', meaning there is zero integrity verification — any substitution of the binary at the source URL would go undetected. While rebolsource.net appears to be the legitimate upstream Rebol project site, the combination of: (1) a directly executed binary, (2) no checksum verification, and (3) an 'experimental' download path constitutes a genuine supply-chain risk. This is a textbook medium: not clearly malicious, but a prebuilt binary from a non-package-repository host with no integrity check.

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, …).
