Why flagged

The PKGBUILD downloads and executes a prebuilt AppImage binary from wlhex.com, which appears to be the vendor's own domain (the app URL is jidugs.wlhex.com and the download is from jidugs.wlhex.com/download/). This is consistent with a small Chinese software vendor hosting their own releases rather than using GitHub releases or a major CDN. The sha256sum is pinned, which mitigates substitution attacks. However, the host is not a well-known, auditable release infrastructure, the software is proprietary with a commercial license, and the AppImage is executed during prepare() via --appimage-extract to unpack it. A compromised or malicious AppImage from this host would result in arbitrary code execution at install time. This is a genuine medium-severity supply-chain concern: a closed-source binary from a small, unverifiable vendor host that is executed during the build process, even though it appears to be the legitimate upstream distribution channel for this product.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
