The vulnerability is similar to CVE-2025-4404, where FreeIPA failed to validate the uniqueness of the krbCanonicalName. In this case, although previous versions had added validation for the admin@REALM credential, they still do not validate the root@REALM canonical name. This name can be used as the realm administrator&#8217;s name.<br \/>\nThe flaw allows an attacker to perform administrative tasks over the REALM, leading to <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2024-12367-system-compromise-via-sensitive-information-exposure-in-vega-master-software\/\"  data-wpil-monitor-id=\"89876\">system control and sensitive<\/a> data exfiltration.
