MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb installer from rinnovofirma.infocert.it, which appears to be an official InfoCert vendor subdomain (InfoCert is a major Italian CA/digital signature provider). The binary is an Electron-based desktop application extracted and installed directly. Key concerns: (1) the source URL points to 'latest' rather than a versioned artifact, meaning the downloaded binary could change without the sha512sum catching it on future builds (though the current build pins the hash); (2) it is a prebuilt closed-source binary from a vendor host, not compiled from source — standard supply-chain risk for AUR binary packages; (3) the sha512sum provided has only 127 hex characters instead of the required 128, which is suspicious and may indicate a truncation error, potentially making integrity verification unreliable. The host itself appears legitimate (official Italian digital signature authority), so this is not clearly malicious, but the combination of a prebuilt binary, a 'latest' URL, and a malformed checksum keeps this at MEDIUM risk.

MEDIUM source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
