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

Details: 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 ### Credits Aytaç Kalıncı, Ilker Bulgurcu, Yasin Yılmaz (@aytackalinci, @smileronin, @yasinyilmaz) - NETAŞ PENTEST TEAM
