MEDIUM

Why flagged The package downloads a prebuilt binary installer (a .run script containing a tar.gz payload) from download.leagsoft.com. This is the official distribution host for UniVPN by Leagsoft (联软科技), a Chinese enterprise security software vendor — leagsoft.com is their actual corporate domain, not a random personal host. The sha256sum is pinned, which mitigates silent substitution risk. However, the package installs a closed-source, prebuilt binary VPN client with no source available for inspection, and the wrapper script runs the binary via pkexec (root), meaning the binary executes with elevated privileges. The binary itself is opaque and from a Chinese enterprise vendor. This is a legitimate medium-risk concern: not because the host is unofficial (it is the vendor's own host), but because an unauditable prebuilt binary is installed and executed as root via pkexec. This is the standard medium-risk pattern for proprietary binary AUR packages.

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, …).
