MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary zip from releases.versiobit.com (a project-specific but unofficial/unverified host) and installs it directly into /opt, symlinking the binary into /usr/bin. Two concrete concerns: (1) sha512sums is SKIP, meaning there is zero integrity verification — any compromise of the release host or a MITM would silently deliver malicious binaries; (2) the installed artifact is a prebuilt executable blob, not source-compiled, so the contents cannot be audited from the PKGBUILD alone. The host is the project's own release server (releases.versiobit.com), which is a common pattern for proprietary desktop apps in the AUR, so this is not clearly malicious. However, the combination of an unverified prebuilt binary from a non-standard host with SKIP checksums constitutes a genuine supply-chain risk, consistent with a MEDIUM rating.

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, …).
