Why flagged

The PKGBUILD downloads a prebuilt binary ZIP archive from docs.smos.online (not the canonical upstream smos.cs-syd.eu domain) and installs its contents directly as executables. There is no signature verification, only a SHA-256 checksum. The host docs.smos.online appears to be a documentation/asset subdomain rather than an official release host, and the commented-out previous checksum suggests the archive has been silently replaced at least once without a pkgver bump. Installing arbitrary prebuilt binaries from a non-canonical host with only a checksum (no GPG signature) is a genuine supply-chain risk: if the host is compromised or the maintainer of that host acts maliciously, users receive and execute untrusted code. This fits the medium severity definition exactly.

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, …).
