CVE-2026-42877 Details
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.
A stored cross-site scripting vulnerability has been identified in FacturaScripts accounting and invoicing software, affecting versions through 2025.92. The issue resides in the product search modal for sales and purchases documents. An authenticated user with access to the warehouse module can create a product with a malicious reference. This reference executes arbitrary JavaScript in the browser of any other user who opens the product search modal within an invoice, order, or delivery note.
The vulnerability can be fixed by applying proper HTML escaping to the product reference before it is inserted into the 'onclick' attribute of the product search modal. Alternatively, the 'innerHTML' property can be replaced with 'innerText' or a DOM-based rendering approach that does not parse strings as HTML.
