Descriptions

Drupal 8.4.x versions before 8.4.5 and Drupal 7.x versions before 7.57 has a Drupal.checkPlain() JavaScript function which is used to escape potentially dangerous text before outputting it to HTML (as JavaScript output does not typically go through Twig autoescaping). This function does not correctly handle all methods of injecting malicious HTML, leading to a cross-site scripting vulnerability under certain circumstances. The PHP functions which Drupal provides for HTML escaping are not affected.

Las versiones 8.4.x de Drupal anteriores a la 8.4.5 y las versiones 7.x anteriores a la 7.57 tienen una función de JavaScript Drupal.checkPlain() que se emplea para escapar texto potencialmente peligroso antes de extraerlo como HTML (ya que la exportación JavaScript no suele pasar un proceso de autoescape Twig). Esta función no gestiona adecuadamente todos los métodos de inyección de HTML malicioso, lo que conduce a una vulnerabilidad de Cross-Site Scripting (XSS) en ciertas circunstancias. Las funciones de PHP que Drupal proporciona para escapar HTML no se han visto afectadas.
