Why flagged
The package downloads and executes an AppImage from a third-party hosting service (todesktop.com) without a verifiable upstream source, creating a supply-chain risk if the host is compromised.
Triggered rules
Medium
External download from an untrusted host, not in source=()
external_download_not_in_source
curl/wget fetches a URL on a non-allowlisted host that is not part of source=(), so it is not checksum-verified by makepkg.
-
PKGBUILD:27
curl -Lo "$_filename" "https://download.todesktop.com/${_todesktop_id}/${_filename}"
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, …).
