Administrator-browser script execution via inline XML files
Published Dec 30, 2025 · Updated Dec 30, 2025
Stored XSS in FacturaScripts before 2025.7 allows remote authenticated users to execute JavaScript in an administrator's browser. Core/Controller/Myfiles.php serves uploaded XML inline because its force-download check covers SVG files but not XML content. A regular account can attach the file to a product, but an administrator must open it; execution is confined to that browser session.
