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.
AnalysisAI
PHP object injection in FacturaScripts before version 2026.7 allows an authenticated attacker to delete arbitrary files on the server, causing denial of service and potentially enabling a reinstall hijack that resets the application. The flaw is reachable through the multiple-select handling path in WidgetSelect::processFormData(), which passes raw POST data to unserialize() without restricting allowed classes; submitting a crafted serialized XLSXWriter object triggers its __destruct() destructor, which performs the file deletion (config.php and backup data are the notable targets). …
