Description Samuele Negrini 2026-07-07 09:09:33 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

When ldap_sudo_search_base is not explicitly configured (the default), SSSD falls back to the domain's root DN and searches the entire LDAP directory tree for objects matching (objectClass=sudoRole) with SUBTREE scope. Any LDAP principal with write access to any subtree can create a sudoRole object granting arbitrary sudo privileges on every SSSD-enrolled host.

This affects sudo_provider = ldap and sudo_provider = ad (which delegates to sdap_sudo_init()). sudo_provider = ipa is NOT affected.
