MEDIUM

Why flagged The package installs a setuid binary (nym-exclude) which grants elevated privileges, a legitimate requirement for some network tools but a potential security risk if misused or 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.

PKGBUILD:57 chmod u+s "$pkgdir/usr/bin/nym-exclude"
