Why flagged

The source is a prebuilt RPM bundle fetched from buzo.eu, which is a personal mirror rather than the official Epson download server (support.epson.net/linux). The package extracts and installs a prebuilt binary (networkscan) directly into /usr/lib/utsushi/. While the sha256sum provides some integrity protection against accidental corruption, it does not protect against the mirror owner silently replacing the artifact with a malicious one, nor does it verify the binary's provenance from Epson. The official Epson source appears to require a bundle download that may not be directly linkable, which explains the personal mirror, but this is still a supply-chain concern: an executed binary from an unofficial host. This is a genuine medium-severity concern, not a false positive.
