Descriptions

PrestaShop is an open-source e-commerce platform. Prior to versions 8.1.3 and 1.7.8.11, some event attributes are not detected by the `isCleanHTML` method. Some modules using the `isCleanHTML` method could be vulnerable to cross-site scripting. Versions 8.1.3 and 1.7.8.11 contain a patch for this issue. The best workaround is to use the `HTMLPurifier` library to sanitize html input coming from users. The library is already available as a dependency in the PrestaShop project. Beware though that in legacy object models, fields of `HTML` type will call `isCleanHTML`.

PrestaShop es una plataforma de comercio electrónico de código abierto. Antes de las versiones 8.1.3 y 1.7.8.11, el método `isCleanHTML` no detecta algunos atributos de eventos. Algunos módulos que utilizan el método `isCleanHTML` podrían ser vulnerables a cross site scripting. Las versiones 8.1.3 y 1.7.8.11 contienen un parche para este problema. La mejor solución es utilizar la librería `HTMLPurifier` para sanitizar la entrada HTML proveniente de los usuarios. La librería ya está disponible como dependencia en el proyecto PrestaShop. Sin embargo, tenga en cuenta que en los modelos de objetos heredados, los campos de tipo `HTML` llamarán `isCleanHTML`.
