Why flagged

The PKGBUILD fetches a manifest JSON from masa.dy.fi (the personal site of the well-known Minecraft modder 'masa', author of mods like MiniHUD, Litematica, etc.) with sha1sums='SKIP', then uses jq to extract a download URL from that manifest and fetches the actual JAR at build time via wget — with no integrity check whatsoever on the downloaded JAR. Two real concerns: (1) the manifest is fetched with SKIP checksum, meaning any MITM or server compromise could redirect the build to an arbitrary JAR; (2) the JAR URL is fully controlled by the manifest content, so a compromised manifest could point wget at any executable. While masa.dy.fi is a legitimate and well-known host for these Minecraft mods (not a random personal host), the complete absence of checksums on both the manifest and the final executed JAR is a genuine supply-chain concern. The pattern of fetching a manifest to derive a URL and then executing the result without verification is inherently risky regardless of the host's reputation. This is a real medium-severity concern, not a false positive.

Triggered rules
