Why flagged

This PKGBUILD downloads a prebuilt binary ZIP from an Aliyun OSS bucket (ishell-down.oss-cn-beijing.aliyuncs.com) — a personal/vendor-controlled object storage bucket rather than an official distribution channel like GitHub releases or a distro mirror. The binary is then installed and symlinked into /usr/bin for execution. The sha256sum provides integrity checking against accidental corruption but does not protect against the bucket owner substituting a malicious binary at the same URL. The host is not a recognized official release infrastructure (no GitHub, no official project CDN with transparent release process), and the package is a closed-source SSH tool with AI features, making the supply-chain risk real: if the OSS bucket is compromised or the owner pushes a malicious update, users execute arbitrary code. This is a textbook medium-severity supply-chain concern: executed binary from an unofficial/personal host with no source transparency.

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, …).
