Отчет
The Red Hat Product Security team has assessed the severity of this vulnerability as Important, given that the attacker must already possess the impersonation role. Successful exploitation allows an attacker to gain full administrative control over the realm. The vulnerability's root cause is a missing privilege-level check on the target user during the impersonation process.
