MEDIUM

Why flagged The PKGBUILD downloads a prebuilt AppImage from installer.rootapp.com, which appears to be the official vendor's CDN/installer host for rootapp.com. The AppImage is executed during prepare() via --appimage-extract to unpack it, and the resulting binaries are installed. The sha256sum is pinned, which mitigates MITM risk, but the URL points to a mutable path (Root.AppImage without version in the path), meaning the checksum could become stale or the file could be silently replaced at the source. This is a standard pattern for binary AppImage packages in the AUR, but the non-versioned URL means the checksum is the only integrity guarantee. The host (installer.rootapp.com) is plausibly the official vendor infrastructure. Overall this is a legitimate medium-risk pattern: executed binary from a vendor host with a fixed checksum but a mutable URL — not clearly malicious, but a real supply-chain concern if the host or the file is ever substituted.

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, …).
