MEDIUM

Why flagged This PKGBUILD downloads a prebuilt proprietary AppImage binary from installer.rootapp.com with SKIP'd checksums (no integrity verification), then installs and executes it. The concerns are: (1) SKIP checksums mean any MITM or server-side substitution goes undetected; (2) the AppImage is executed during package() to extract icons (--appimage-extract), meaning arbitrary code runs at build time; (3) installer.rootapp.com is the vendor's own installer subdomain, not a well-known mirror, and 'rootapp' is an obscure/unverified proprietary application. The validpgpkeys entry is present but never actually used to verify the downloaded AppImage (there is no sig source). This is a genuine supply-chain concern: an executed binary from an unverified host with no checksum. Not clearly malicious, but a real medium-severity risk.
