MEDIUM

Why flagged The PKGBUILD downloads a prebuilt JAR file from 'alist.8mi.tech', which is a personal/third-party mirror host, not the official GitHub releases infrastructure for the HMCL project (github.com/burningtnt/HMCL or the canonical HMCL repo). The JAR is executed as a Java application (installed to /usr/share/java and launched via a script), so a compromised or substituted JAR could achieve code execution. Additionally, all sha256sums are 'SKIP', meaning there is zero integrity verification — any file served by that host would be accepted without validation. This is a genuine supply-chain concern: the combination of an unofficial third-party host, an executable artifact (JAR), and no checksum verification represents a real medium-severity risk. It is not clearly malicious, but the trust chain is broken.

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, …).
