MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary .deb from oss-cn-hangzhou.aliyuncs.com (Alibaba Cloud OSS), which is plausibly the official Aliyun SASE client distribution channel. However, the URL uses a 'latest' path component (sase-app-latest.deb) rather than a versioned artifact path, meaning the actual file served could change at any time on the server side — the sha256sum only protects against network tampering at download time but does not guarantee the file matches the declared pkgver=3.4.2. The package installs a closed-source VPN/network-access client binary plus a systemd service that runs at boot, giving it persistent elevated network access. The combination of: (1) a prebuilt closed-source binary, (2) a mutable 'latest' URL that could serve a different binary than what was checksummed, and (3) a systemd service granting persistent system-level network access constitutes a genuine supply-chain concern. The sha256sum mitigates the risk somewhat but the mutable URL pattern is a real weakness. This is a legitimate medium-severity concern, not a false positive.
