A flaw was found in Keycloak. This flaw allows a privileged attacker to use the malicious payload as the group name while creating a new group from the admin console, leading to a stored Cross-site scripting (XSS) attack.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
