CVE-2026-14474 (opens in a new tab)How to fix?
Upgrade sssd to version 2.14.0-beta1 or higher.
Overview
Affected versions of this package are vulnerable to Insecure Default Initialization of Resource due to the default behavior of the ldap_sudo_search_base configuration, which causes the entire directory tree to be searched for sudoRole objects. An attacker can gain unauthorized root-level privileges on all enrolled hosts by injecting a sudoRole object into any writable subtree. This is only exploitable if the attacker has delegated LDAP write access to any subtree and the ldap_sudo_search_base is not explicitly set.
Workaround
This vulnerability can be mitigated by explicitly setting ldap_sudo_search_base in /etc/sssd/sssd.conf to restrict the search to the designated sudoers container and by restricting LDAP ACLs to prevent non-admin principals from creating sudoRole objects outside the designated sudoers container.
