YunaiV yudao-cloud transfer improper authorization

A weakness has been identified in YunaiV yudao-cloud up to 2025.09. This affects an unknown part of the file /crm/business/transfer. Executing a manipulation of the argument ids/newOwnerUserId can lead to improper authorization. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. It is recommended to upgrade the affected component. The vendor confirms: "[T]he current code already checks the functional update permission, uses the authenticated server-side user ID, requires CRM OWNER permission, and explicitly rejects non-owner transfers in the shared transfer service, except for authorized CRM administrators."
