CVE-2026-9795 (opens in a new tab)How to fix?
Upgrade org.keycloak:keycloak-services to version 26.6.3 or higher.
Overview
org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Incorrect Privilege Assignment via improper enforcement of scope mapping in the Fine-Grained Admin Permissions (FGAPv2) feature due to ScopeMappedResource and ScopeMappedClientResource write endpoints missing a call to requireMapClientScope per role. An attacker can gain unauthorized access to privileged roles by injecting arbitrary realm roles into a client's scope, which are then projected into a user's authentication token upon login through the compromised client. This is only exploitable if Fine-Grained Admin Permissions (FGAPv2) are enabled and the attacker has fine-grained client management permissions, and a privileged user subsequently authenticates through the affected client.
