MEDIUM

Why flagged A prebuilt AppImage binary is downloaded from moltorino.com (a personal/project site, not a well-known official distribution channel like GitHub releases), with sha256sums='SKIP', meaning no integrity verification whatsoever. The AppImage is also executed during prepare() via --appimage-extract, and then installed and run as the final application. The combination of an unverified binary from a non-major host that is both extracted and executed represents a genuine supply-chain risk: if moltorino.com is compromised or the maintainer is malicious, arbitrary code runs on the user's machine with no checksum protection. This is a textbook medium-severity AUR concern — not clearly malicious, but a real code-execution risk from an unofficial host with no integrity check.

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, …).
