MEDIUM

Why flagged The PKGBUILD downloads a prebuilt proprietary binary .deb from a Google Cloud Storage bucket (storage.googleapis.com/world-radio-league-prod.appspot.com) and installs it directly. The core concern is: (1) all sha256sums are SKIP, meaning there is zero integrity verification — any substitution of the binary would go undetected; (2) it is a prebuilt executable from a non-standard/vendor-controlled cloud storage host rather than a well-known official release page with published checksums. The GCS bucket name suggests it is the vendor's own storage (world-radio-league-prod.appspot.com), which is plausible for a small proprietary software vendor, but there is no way to verify this without published checksums. The combination of an executed binary + SKIP checksums is a genuine supply-chain risk (not just sloppy packaging), warranting medium severity. It is not high because there is no evidence of active malice, obfuscation, or exfiltration — it appears to be a legitimate but poorly packaged proprietary application.
