Summary

A flaw was found in the SAML client registration in Keycloak that could allow an administrator to register malicious JavaScript URIs as Assertion Consumer Service POST Binding URLs (ACS), posing a Cross-Site Scripting (XSS) risk.

This issue may allow a malicious admin in one realm or a client with registration access to target users in different realms or applications, executing arbitrary JavaScript in their contexts upon form submission. This can enable unauthorized access and harmful actions, compromising the confidentiality, integrity, and availability of the complete KC instance.

Red Hat severity: Moderate — CVSS 6 (CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:L). Weakness: CWE-79.

Affected Red Hat products: Red Hat AMQ Broker 7; Red Hat build of Keycloak 22; Red Hat build of Keycloak 22.0.10; RHOSS-1.33-RHEL-8; RHPAM 7.13.5 async; Migration Toolkit for Applications 6; Red Hat build of Apicurio Registry 2; Red Hat Data Grid 8; Red Hat Decision Manager 7; Red Hat Fuse 7; Red Hat JBoss Data Grid 7; Red Hat JBoss Enterprise Application Platform 6; Red Hat OpenShift GitOps; Red Hat Process Automation 7; Red Hat Single Sign-On 7.
