MEDIUM

Why flagged The package downloads and installs a prebuilt binary from a personal/project host (fedi.doom.solutions) rather than a well-known release platform (GitHub releases, official vendor CDN, etc.). The binary is executed directly as /usr/bin/tumelune. While sha256sums are present (providing integrity against accidental corruption or CDN substitution), they do not protect against the host owner replacing the binary with a malicious one and updating the PKGBUILD simultaneously. The host appears to be the maintainer's own server hosting a personal project, which is a legitimate but non-standard pattern. This is a real supply-chain concern: if the host is compromised or the maintainer is malicious, users get arbitrary code execution. This fits the medium category — not clearly malicious, but an executed binary from an unofficial personal host.

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, …).
