Descriptions

In Drupal 8.x prior to 8.3.7 When creating a view, you can optionally use Ajax to update the displayed data via filter parameters. The views subsystem/module did not restrict access to the Ajax endpoint to only views configured to use Ajax. This is mitigated if you have access restrictions on the view. It is best practice to always include some form of access restrictions on all views, even if you are using another module to display them.

En Drupal, en sus versiones 8.x anteriores a la 8.3.7, cuando se crea una vista se puede usar Ajax de manera opcional para actualizar los datos mostrados mediante parámetros filter. Las vistas "subsystem" y "module" no restringían el acceso al endpoint de Ajax a visualizaciones configuradas para usar Ajax. Esto se puede mitigar si se tienen restricciones de acceso en la previsualización. Es una buena práctica siempre incluir algún tipo de restricciones de acceso en todas las visualizaciones, incluso aunque se utilice otro módulo para mostrarlas.
