CVE-2016-8629
An attacker with service account authentication could use this flaw to bypass normal permissions and delete users in a separate realm.
Does this matter?
Lower severity and a low EPSS score (1.90%). Track it; it rarely justifies an emergency change on its own.
Description
Red Hat Keycloak before version 2.4.0 did not correctly check permissions when handling service account user deletion requests sent to the rest server. An attacker with service account authentication could use this flaw to bypass normal permissions and delete users in a separate realm.
