Description

FacturaScripts is an open source accounting and invoicing software. In 2025.92 and earlier, a stored Cross-Site Scripting (XSS) vulnerability exists in the product search modal of sales (Core/Lib/AjaxForms/SalesModalHTML.php) and purchases documents (Core/Lib/AjaxForms/PurchasesModalHTML.php). An authenticated user with access to the warehouse module can create a product with a malicious reference that executes arbitrary JavaScript in the browser of any other user who opens the product search modal inside an invoice, order, or delivery note.
