MEDIUM

Why flagged The package downloads a prebuilt binary tarball from a CloudFront CDN URL (d148mrbia1nlbw.cloudfront.net) rather than from GitHub releases or the official monarchapp.io domain. This CloudFront distribution appears to be Monarch's own distribution infrastructure (the project uses CloudFront to host its binaries, consistent with their documented install instructions), so this is not a random personal host. However, it is still an unofficial-looking URL with no way to verify the CDN is controlled by the upstream project without external research, and prebuilt binaries are executed directly. The sha256sums are pinned, which mitigates substitution risk significantly. The LICENSE is fetched from the official GitHub repo. Overall this is a legitimate but slightly non-standard distribution pattern (vendor CDN rather than GitHub releases), with pinned checksums reducing supply-chain risk. The medium rating is borderline but defensible given the executed binary from a CDN whose ownership is not self-evident from the PKGBUILD alone.

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, …).
