lext-theme-lubuntu-arc
The source tarball is fetched from a personal DuckDNS dynamic-DNS host (lext-store.duckdns.org), which is not an official distribution channel, a well-known mirror, or a language-ecosystem registry. DuckDNS domains are free, ephemeral, and can be reassigned, making this a genuine supply-chain concern: the host could change ownership or be compromised without any indication in the PKGBUILD. Compounding this, the sha256sum is explicitly set to 'SKIP' with a comment saying it's 'for testing', meaning there is zero integrity verification on the downloaded archive. The tarball is then unpacked and its contents copied directly into the package root (cp -r srcdir/usr pkgdir), so any executable, library, or configuration file inside the archive is installed without inspection. The combination of an unofficial dynamic-DNS host and a skipped checksum on an installed binary/data archive is a real, if not clearly malicious, supply-chain risk — consistent with a MEDIUM rating.
