MEDIUM

Why flagged The package downloads a prebuilt Windows executable from a non-standard host (assets.mubu.com) which is not a common source for AUR packages, and although it's the project's own domain, the executable is unpacked and repackaged, creating a supply-chain risk if the source were compromised.

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, …).
