A flaw has been found in feelec-yishu feelcrm-os 1.0.0. Affected is an unknown function of the file App/Feelcrm/Crm/Controller/AjaxRequestController.class.php of the component getMemberByGroups Endpoint. This manipulation of the argument groups[] causes sql injection. The attack is possible to be carried out remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
