MEDIUM

Why flagged A prebuilt x86_64 binary is fetched from a personal DDNS host (dexieldvpn.ddns.net) rather than from the GitHub releases page listed as the upstream URL. DDNS hostnames are dynamic and can be reassigned; the host is not an official or well-known distribution mirror. While a sha256 checksum is present, it only verifies the current content — if the host is compromised or the DNS entry is redirected, a future user gets a different binary with no integrity guarantee (AUR helpers re-download on each install). The binary is installed directly into /usr/bin and executed as a user-space program, so any malicious payload would run with user privileges. The mismatch between the stated upstream (GitHub) and the actual download host is a genuine supply-chain concern: there is no verifiable chain of custody from source code to binary. This is a textbook medium-severity case: an executed binary from an unofficial/personal host.

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
