Why flagged

A prebuilt binary (Electron/native app bundle) is downloaded from downloads.samidy.com, a third-party host unrelated to the official GitHub repository, and installed directly to /opt and executed via a wrapper script. The checksum is SKIP'd, meaning there is zero integrity verification. If samidy.com is compromised, serves a different binary, or the maintainer of that host acts maliciously, users will silently execute arbitrary code. This is a textbook supply-chain risk: executed binary from an unofficial/personal host with no checksum. The GitHub URL is only used for pkgver() and the icon, not for the actual application binary. Medium severity is correct.

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, …).
