Описание
A flaw was found in the Keycloak identity and access management system when Fine-Grained Admin Permissions(FGAPv2) are enabled. An administrative user with the manage-users role can escalate their privileges to realm-admin due to improper privilege enforcement. This vulnerability allows unauthorized elevation of access rights, compromising the intended separation of administrative duties and posing a security risk to the realm.
Отчет
The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate. While the flaw requires an already privileged user, with manage-users, and an FGAPv2-enabled realm, successful exploitation allows complete administrative takeover of a Keycloak realm. This could lead to unauthorized changes to users, roles, and realm configurations. The vulnerability is particularly concerning in environments where multiple administrative users have restricted scopes.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
