## How to fix

- Fixed in FacturaScripts 2026.7

## Technical details

WidgetSelect::processFormData() unsafely calls unserialize() on raw POST data without an allowed_classes filter when processing multiple-select form fields. An attacker can submit a serialized XLSXWriter object that triggers arbitrary file deletion via the gadget's __destruct() method, which calls unlink() on attacker-controlled file paths. The vulnerability requires an authenticated session to access an edit form containing a multiple="true" select field.
