MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from download.mementodb.com, which is the official vendor download host for Memento Database (mementodatabase.com). The host appears to be the legitimate upstream distribution channel for this proprietary application, not a personal or unofficial mirror. However, the package still installs a prebuilt binary blob (a Java-based desktop application) extracted from a .deb, with only a sha256sum for integrity verification and no GPG signature check. This is a standard pattern for proprietary Linux applications distributed as .deb packages (similar to how many AUR packages handle Chrome, Slack, etc.), but the absence of signature verification and the reliance on a single vendor-controlled host means a compromised host or MITM could substitute malicious binaries. The sha256sum provides some protection against accidental corruption but not against a deliberate substitution at the source. This warrants medium severity due to the executed binary nature of the content, not because the host is clearly malicious or unofficial.

Triggered rules

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, …).
