Why flagged

Installs a self-update script with sudo privileges via /etc/sudoers.d, enabling privilege escalation for automated updates, which is a supply-chain risk if the update mechanism is compromised.

Triggered rules

Medium Privileged / out-of-pacman install (sudoers, setuid, or self-update) privileged_install

The package grants elevated privileges or installs an update path outside pacman: a /etc/sudoers.d rule (often passwordless), a setuid/setgid binary, or a self-update script/service that can fetch and run future code with no checksum verification. The initial install may be verified, but the ongoing privilege + update surface is a real supply-chain / privilege-escalation risk.
