An administrator with limited client management permissions can exploit this vulnerability to assign any realm role, including highly privileged roles, to a client's scope mapping. This bypasses intended security controls, allowing the injected role to be projected into a user's authentication token when they access the modified client. This could lead to unauthorized privilege escalation within the Keycloak realm.\n\n## Affected packages\n\n- `org.keycloak:keycloak-services < 26.6.4`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `org.keycloak:keycloak-services 26.6.4`","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":40.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
