MEDIUM

Why flagged The PKGBUILD downloads a prebuilt AppImage binary from cdn.icedrive.net (the official Icedrive CDN, not a personal/unofficial host) and executes it during the build phase (--appimage-extract). The host appears to be the legitimate vendor CDN for Icedrive cloud storage. However, sha512sums=('SKIP') means there is no integrity verification whatsoever — if the CDN is compromised, the download is intercepted (MITM), or the URL is silently redirected, an arbitrary binary would be executed on the build system and installed. This is a genuine supply-chain concern: an executed binary with no checksum. The host being the official vendor CDN reduces but does not eliminate the risk (CDNs can be compromised, and HTTPS alone is not a substitute for a pinned hash). This is a textbook medium-severity AUR pattern: prebuilt binary from a plausible official source but with SKIP checksum.

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, …).

An AI model (anthropic/claude-4.6-sonnet-20260217) reviewed this and agrees it is MEDIUM (confidence 72%): The PKGBUILD downloads a prebuilt AppImage binary from cdn.icedrive.net (the official Icedrive CDN, not a personal/unofficial host) and executes it during the build phase (--appimage-extract).
