Summary

FacturaScripts before version 2026.7 contains a PHP object injection vulnerability in WidgetSelect::processFormData() that allows authenticated attackers to trigger unserialize() on raw POST data without an allowed_classes filter for multiple-select fields. Attackers can submit a serialized XLSXWriter object as the field value to invoke its __destruct() method, deleting arbitrary attacker-specified files such as config.php or backup data, resulting in denial of service and potential application reinstall hijack.
