MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary .deb from cdn.scholaread.com (the vendor's own CDN, not a personal/unofficial host) and installs it directly. The main concerns are: (1) sha256sums=('SKIP') means no integrity verification — any compromise of the CDN or a MITM attack would silently deliver malicious binaries; (2) the package installs a setuid-root binary (chrome-sandbox with chmod 4755), which is a high-privilege operation; (3) it's a closed-source Electron app binary with no source verification. However, cdn.scholaread.com appears to be the official vendor CDN for the scholaread.com product, making this more of a standard 'binary from vendor' AUR pattern rather than a clearly unofficial/personal host. The SKIP checksum is the real concern — it means every install fetches whatever is currently at that URL with no pinning. This is a genuine supply-chain risk (medium) but not evidence of active malice.
