MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary tarball (wowmatrix or wowmatrix32) from swupdate.wowmatrix.com over plain HTTP with checksums set to SKIP, then installs the extracted binary directly to /usr/bin. This is a real supply-chain concern: (1) no integrity verification whatsoever on the executed binary, (2) plain HTTP allows MITM substitution, (3) swupdate.wowmatrix.com is the vendor's own update subdomain rather than a well-known mirror, so while it is the official vendor host it is not a standard distribution channel. The combination of an executed binary + SKIP checksums + plain HTTP is a genuine medium-severity risk. It is not high because there is no evidence of malice or obfuscation — this appears to be a legitimate proprietary freeware application — but the lack of any integrity check on an installed binary is a real packaging deficiency with supply-chain implications.
