MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary from an unofficial S3 bucket (wpeclibinaries) controlled by an unknown party rather than from the official WP Engine GitHub releases or a verified vendor CDN. The binary is then installed as an executable. While an MD5 checksum is present, MD5 is cryptographically broken and provides minimal protection against a targeted substitution attack. The S3 bucket name 'wpeclibinaries' is not verifiably tied to WP Engine's official infrastructure, and there is no GPG signature verification. This is a genuine supply-chain concern: a prebuilt binary from an unverified third-party host is installed directly into /usr/local/bin. This matches the classic medium-severity pattern of an executed binary from an unofficial/personal host.
