Descriptions

Some field types do not properly sanitize data from non-form sources in Drupal 8.5.x before 8.5.11 and Drupal 8.6.x before 8.6.10. This can lead to arbitrary PHP code execution in some cases. A site is only affected by this if one of the following conditions is met: The site has the Drupal 8 core RESTful Web Services (rest) module enabled and allows PATCH or POST requests, or the site has another web services module enabled, like JSON:API in Drupal 8, or Services or RESTful Web Services in Drupal 7. (Note: The Drupal 7 Services module itself does not require an update at this time, but you should apply other contributed updates associated with this advisory if Services is in use.)

Algunos tipos de campos no sanean correctamente los datos provenientes de fuentes "non-form" en Drupal en sus versiones 8.5.x anteriores a la 8.5.11 y en las versiones 8.6.x anteriores a la 8.6.10. Esto puede provocar, en algunos casos, la ejecución de código PHP. Un sitio solo se ve afectado por esto si se cumple una de las siguientes condiciones. Este sitio tiene el módulo Drupal 8 core RESTful Web Services (rest) habilitado y permite peticiones PATCH o POST, o el sitio tiene otro módulo de servicios web habilitado, como JSON:API en Drupal 8 o Services o RESTful Web Services en Drupal 7. (Nota: El módulo de Drupal 7 Services mismo no precisa una actualización en este momento. Sin embargo, se deberían instalar otras actualizaciones contribuidas que estén asociadas con este aviso si "Service" se encuentra en uso.)

In Drupal Core, some field types do not properly sanitize data from non-form sources. This can lead to arbitrary PHP code execution in some cases.
