Описание
A flaw was found in Keycloak. An authenticated user with existing organization membership can exploit this flaw by accessing user-facing APIs, such as the account API or by requesting an OpenID Connect (OIDC) token with the 'organization' scope. This allows organization metadata to be disclosed in tokens, even after an administrator has explicitly disabled the Organizations feature, potentially leading to incorrect authorization decisions by resource servers.
Отчет
Keycloak fails to enforce the disabled state of the Organizations feature on user-facing APIs, allowing authenticated users to retrieve organization membership data and obtain tokens with organization claims even after an administrator has disabled the feature at the realm level.
Меры по смягчению последствий
Administrators should verify that disabling the Organizations feature properly blocks all organization-related functionality. Consider implementing additional access controls or removing organization memberships before disabling the feature.
