A flaw was found in Keycloak. A limited administrator can exploit an improper access control vulnerability in the POST /admin/realms/{realm}/partialImport endpoint. This allows them to bypass Fine-Grained Admin Permissions (FGAP) and escalate their privileges to a full realm administrator by importing users with realm-admin role mappings.
