ELADMIN (eladmin-mp) up to 2.7 contains an improper access control vulnerability in the role management module. The endpoint PUT /api/roles/menu (RoleController.updateRoleMenu) authorizes the request only by comparing the target role's level with the caller's minimum level. The application neither validates the granted menu set nor prevents a caller from modifying its own role. A logged-in non-admin user whose role holds the delegated roles:edit permission can submit its own role id together with an arbitrary list of menu ids.
