## Technical details

The vulnerability is an authorization bypass in the SysUserServiceImpl.selectUserListByDept endpoint (accessed via GET /system/user/list/dept/{deptId}). Authenticated users holding the system:user:list permission for their own department can request arbitrary department IDs and retrieve complete user information, circumventing department-level access controls. The flaw allows horizontal privilege escalation across department boundaries without additional authentication.
