MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary (kakele-linux.zip containing a native executable 'kakele' and a JAR) from the official game's CDN (kakele.nyc3.cdn.digitaloceanspaces.com), which is the vendor's own DigitalOcean Spaces bucket — consistent with how indie game developers distribute binaries. However, the checksum is 'SKIP', meaning there is no integrity verification of the downloaded binary. The URL points to 'latest' (a mutable path), so the file can be silently replaced at any time without the PKGBUILD changing. This is a real supply-chain concern: a compromised or swapped binary at that URL would be installed and executed with no checksum to catch it. The host appears to be the official vendor CDN rather than a random personal host, which reduces (but does not eliminate) the risk. The combination of a mutable 'latest' URL and SKIP checksum for an executed binary warrants a medium rating.

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, …).
