MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary tarball (containing xump_ubuntu32 and xump_ubuntu64 executables) directly from retroguru.com using a 'v.latest' URL that always resolves to the current version — meaning the sha256sum could become stale/mismatched if the upstream silently updates the file. retroguru.com is the official project host for this freeware game (it is the canonical distribution site for Xump/The Final Run by Retroguru), so this is not a random personal host. However, the binary is a prebuilt executable from a third-party host with no source code available for inspection, and the 'v.latest' URL pattern means the checksum may not pin a specific release. The sha256sum does provide some integrity guarantee at packaging time, but silent upstream binary replacement would not be caught until the next pkgrel bump. This is a real but low-severity supply-chain concern: a prebuilt binary from a non-major forge, with a floating 'latest' URL. The cheaper model's MEDIUM rating is defensible but arguably borderline; the official project host and presence of checksums mitigate the risk somewhat.

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, …).
