Drupal core - Critical - Access bypass - SA-CORE-2019-008

Project:       Drupal core

Date:          2019-July-17

Security risk: Critical 17/25

Vulnerability: Access bypass

CVE IDs:       CVE-2019-6342


In Drupal 8.7.4, when the experimental Workspaces module is enabled, an access
bypass condition is created.

This can be mitigated by disabling the Workspaces module. It does not affect
any release other than Drupal 8.7.4.

Drupal 8.7.3 and earlier, Drupal 8.6.x and earlier, and Drupal 7.x are not 


If the site is running Drupal 8.7.4, upgrade to Drupal 8.7.5.

Note, manual step needed. For sites with the Workspaces module enabled,
update.php needs to run to ensure a required cache clear. If there is a reverse
proxy cache or content delivery network (e.g. Varnish, CloudFlare) it is also
advisable to clear these as well.
