Why flagged

The PKGBUILD downloads a prebuilt binary zip from cli.rescribe.dev (a personal/project subdomain, not a major distribution channel), extracts and installs a native binary (rescribe) and a native Node.js addon (nodegit.node), and also executes a postinstall.sh script from within the zip at build time. There is no PGP signature verification, only an MD5 checksum (which is weak and trivially collided). The combination of: (1) a prebuilt binary from an unofficial host, (2) a native .node addon (which is a shared library executed in-process), and (3) execution of an arbitrary shell script (postinstall.sh) extracted from the same untrusted zip, constitutes a genuine supply-chain risk. If the host or the zip is compromised, arbitrary code runs during package installation. This is a textbook medium-severity supply-chain concern.

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, …).
