SSSD LDAP Sudo Escalation: Unconfigured Search Base Allowing Root Privileges
CVE-2026-14474 Published on July 7, 2026

Sssd: sssd: sudo ldap provider searches entire directory tree for sudorole objects by default, enabling privilege escalation
A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts.
