CVE-2026-19843

389-ds-base: 389-ds-base: command injection via unescaped ldap dn in cockpit 389 console ldap editor

State: Published
Severity: 8.4 High
Published: Sep 7, 2026

Description

A flaw was found in 389-ds-base. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by embedding an LDAP entry's distinguished name (DN) into a shell command string without proper escaping. An LDAP user with delegated privileges to create or rename directory entries could craft a malicious DN containing shell metacharacters. When a Cockpit administrator subsequently views the entry in the 389 Console, the embedded shell command executes with root privileges on the directory server host.
