Why flagged

The PKGBUILD downloads a ZIP archive from developer.apple.com at build time via curl (not in source=()) with no checksum verification, then compiles and installs the resulting library. While developer.apple.com is Apple's official domain, the dynamic download pattern bypasses makepkg's integrity verification entirely — the downloaded binary/source content is never checksummed. The source is Apple's official corecrypto security library release page, which is a legitimate upstream, but the lack of a pinned checksum means any change to what Apple serves (or a MITM) would go undetected. This is a genuine supply-chain hygiene concern (executed compiled code from a dynamically fetched, unverified archive) that justifies MEDIUM. It is not HIGH because the host is Apple's official developer domain, not a personal/unofficial host, and there is no obfuscation or clearly malicious intent.

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:21 curl -s 'https://developer.apple.com/file/?file=security&agree=Yes' \
