    Summary:

    Details: Access bypass vulnerability in of Drupal Core Workspaces allows an attacker to access data without correct permissions.

This vulnerability is mitigated by the fact that sites are only vulnerable if they have installed the experimental Workspaces module. This issue affects Drupal Core8.8.X versions prior to 8.8.10; 8.9.X versions prior to 8.9.6; 9.0.X versions prior to 9.0.6.
