Why flagged

This PKGBUILD downloads a prebuilt binary tarball from cnblogs.com (a Chinese blogging platform, not the project's official GitHub release infrastructure) with md5sums='SKIP' (no integrity verification), then executes an arbitrary install.sh script from inside that tarball with root-level package() privileges. The combination of: (1) an unofficial, unverified binary blob from a personal blog host, (2) no checksum validation whatsoever, and (3) execution of a bundled shell script that can do anything to the system, constitutes a genuine supply-chain risk that goes beyond a typical MEDIUM concern. If cnblogs.com is compromised or the file is replaced, arbitrary code runs during package installation. This is effectively an unverified binary installer pattern — the executed shell script from an untrusted host with no integrity check elevates this to HIGH.

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, …).

High AI review of an ambiguous pattern llm_review

The static rules found a suspicious pattern they could not resolve, so an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed it and judged it HIGH (confidence 92%): This PKGBUILD downloads a prebuilt binary tarball from cnblogs.com (a Chinese blogging platform, not the project's official GitHub release infrastructure) with md5sums='SKIP' (no integrity verification), then executes an arbitrary install.sh script from inside that tarball with root-level package() privileges.
