Descriptions

In PrestaShop contactform module (prestashop/contactform) before version 4.3.0, an attacker is able to inject JavaScript while using the contact form. The `message` field was incorrectly unescaped, possibly allowing attackers to execute arbitrary JavaScript in a victim's browser.

En el módulo contactform de PrestaShop (prestashop/contactform) versiones anteriores a 4.3.0, un atacante puede inyectar JavaScript mientras usa el formulario de contacto. El campo "message" estaba sin escapar incorrectamente, lo que posiblemente permitió a atacantes ejecutar JavaScript arbitrario en el navegador de la víctima
