MEDIUM

Why flagged This PKGBUILD downloads a prebuilt proprietary binary archive (Rocrail-debian11-i64.zip) from wiki.rocrail.net with md5sums='SKIP', meaning the binary is completely unverified at install time. While wiki.rocrail.net appears to be the official Rocrail project wiki/distribution host (the package url matches), the SKIP checksum means any MITM or server-side substitution would go undetected. The archive is extracted and installed as executable binaries under /opt/rocrail, and a wrapper script launches them. The combination of an executed prebuilt binary with no integrity verification is a genuine supply-chain concern — if the host is compromised or the download is intercepted, arbitrary code runs on the user's system. This is a real medium-severity issue: not clearly malicious, but an unverifiable executed binary from a host that, while plausibly official, is not a well-known package mirror with independent verification.
