Keycloak vulnerable to Stored Cross site Scripting (XSS) when loading default roles

A Stored XSS vulnerability was reported in the Keycloak Security mailing list, affecting all the versions of Keycloak, including the latest release (18.0.1). The vulnerability allows a privileged attacker to execute malicious scripts in the admin console, abusing of the default roles functionality.

CVSS 3.1 - 3.8

Vector String: AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N

Vector Clarification:

• User interaction is not required as the admin console is regularly used during an administrator's work
• The scope is unchanged since the admin console web application is both the vulnerable component and where the exploit executes
