Description

The Workspaces module doesn't sufficiently check access permissions when switching workspaces, leading to an access bypass vulnerability. An attacker might be able to see content before the site owner intends people to see the content. 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.
