MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb (a smart card middleware/driver library) from cmcps.it, which is not the official vendor (bit4id.com). The package is extracted and installed directly without any integrity verification beyond a single md5sum (which is weak). Smart card middleware runs with elevated privileges and interfaces with cryptographic hardware, making supply-chain integrity especially critical. cmcps.it appears to be an Italian IT services company, not the upstream vendor, so this is a third-party binary redistribution. There is no sha256sum or GPG signature verification. This is a genuine medium-severity supply-chain concern: an executed binary/library from an unofficial host with only weak checksum verification.
