MEDIUM

Why flagged This PKGBUILD downloads a prebuilt AppImage binary from oss.hexhub.cn, which is the vendor's own CDN/OSS host (matching the official site hexhub.cn), extracts it, and installs the contents. The host is not a well-known, independently verifiable mirror, but it does appear to be the vendor's own storage bucket. The core concern is that a prebuilt binary is being executed (chmod +x and --appimage-extract runs the AppImage), and the entire extracted contents are installed to /opt. There is a sha256sum check, which mitigates silent substitution to some degree, but the binary itself is opaque and unauditable. This is a classic medium-risk pattern: a closed-source prebuilt binary from a vendor-controlled but non-mainstream host, with no source build. Not clearly malicious, but a genuine supply-chain concern.
