——– DESCRIPTION
———————————————————

…. Views – Access Bypass – Moderately Critical – Drupal 8 – CVE-2017-6923

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.

…. REST API can bypass comment approval – Access Bypass – Moderately
Critical – Drupal 8 – CVE-2017-6924

When using the REST API, users without the correct permission can post
comments via REST that are approved even if the user does not have permission
to post approved comments.

This issue only affects sites that have the RESTful Web Services (rest)
module enabled, the comment entity REST resource enabled, and where an
attacker can access a user account on the site with permissions to post
comments, or where anonymous users can post comments.

…. Entity access bypass for entities that do not have UUIDs or have
protected revisions – Access Bypass – Critical – Drupal 8 –
CVE-2017-6925

There is a vulnerability in the entity access system that could allow
unwanted access to view, create, update, or delete entities. This only
affects entities that do not use or do not have UUIDs, and entities that have
different access restrictions on different revisions of the same entity.
