MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from static.retrovm.org (the project's own static hosting subdomain, not a personal/unofficial host) and installs it directly. There is a sha256sum check, which mitigates casual tampering, but the binary is not reproducible from source and comes from a project-controlled CDN rather than a major distribution mirror. The main concern is that if static.retrovm.org were compromised or the maintainer swapped the file at the same URL, the sha256 would catch it only if the PKGBUILD is updated — but the hash is pinned to a specific version, so this is a reasonable supply-chain concern for a closed-source emulator distributed as a prebuilt binary. This is a legitimate medium: executed binary from a non-standard (though project-affiliated) host, no source build, closed-source license. Not high because there is no evidence of malice, the domain matches the project URL, and the hash is pinned.

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