What is CVE-2017-6923?

CVE-2017-6923 is a medium-severity missing authorization vulnerability in Drupal Drupal, published on 22 Jan 2019. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

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.

Weakness: CWE-862
