CVE-2026-59681Network attack vectorHinoki check available

Root command execution via unquoted AD configuration

Published Sep 1, 2026 · Updated Sep 2, 2026

OS command injection in SUSE yast2-auth-client 5.0.4 and earlier allows remote attackers to execute arbitrary commands as root. Auth::AuthConf interpolates unvalidated Active Directory OU, DNS hostname, user, and domain values into Samba command strings passed to Open3, invoking /bin/sh. Exploitation requires a privileged operator to apply attacker-controlled Active Directory settings; the injected shell command then runs as root.
