CVE-2026-19843Network attack vector

Root command execution via unescaped LDAP DN

Published Sep 7, 2026 · Updated Sep 8, 2026

OS command injection in Red Hat Directory Server 11 through 13 allows remote authenticated users to execute commands as root via a crafted LDAP DN. The Cockpit 389 Console LDAP editor inserts the raw DN into a double-quoted ldapsearch shell command sent through Cockpit's superuser channel. Exploitation requires delegated LDAP create or rename rights and a separate privileged Cockpit operator to view the malicious entry; plain RHEL installations are unaffected.
