Descriptions

Winter is a free, open-source content management system. Prior to 1.2.4, Users with access to backend forms that include a ColorPicker FormWidget can provide a value that would then be rendered unescaped in the backend form, potentially allowing for a stored XSS attack. This issue has been patched in v1.2.4.

Winter es un sistema de gestión de contenidos gratuito y de código abierto. Antes de 1.2.4, los usuarios con acceso a formularios de backend que incluyen un FormWidget ColorPicker pueden proporcionar un valor que luego se mostraría sin formato de escape en el formulario de backend, lo que podría permitir un ataque XSS almacenado. Este problema se solucionó en la versión 1.2.4.
