MEDIUM

Why flagged The PKGBUILD downloads a prebuilt AppImage binary from pkgs.reqable.com inside prepare() using wget rather than declaring it in source=() with a checksum. This means: (1) makepkg cannot verify integrity — there is no sha256sum or b2sum check on the downloaded binary, so a compromised or swapped binary would go undetected; (2) the download happens at build time outside of makepkg's normal source-fetching and verification pipeline. The host (pkgs.reqable.com) appears to be the official Reqable distribution server, which reduces but does not eliminate the risk — the real concern is the complete absence of any integrity check on an executed binary. This is a genuine supply-chain concern: a MITM or server compromise could silently deliver a malicious AppImage. Additionally, the package() function references srcdir/squashfs-root which is never created (the AppImage is never extracted with --appimage-extract), making the package likely broken as well, but the security concern stands regardless.

Triggered rules

MEDIUM External download from an untrusted host, not in source=() external_download_not_in_source

curl/wget fetches a URL on a non-allowlisted host that is not part of source=(), so it is not checksum-verified by makepkg.

PKGBUILD:19 wget "https://pkgs.reqable.com/download/reqable-app-linux-x86_64.AppImage?platform=linux&arch=x86_64&version=${pkgver}&ext=AppImage" -O ${srcdir}/${_archive}.AppImage
