CVE-2024-55634: Drupal core Access bypass

Drupal’s uniqueness checking for certain user fields is inconsistent depending on the database engine and its collation. As a result, a user may be able to register with the same email address as another user. This may lead to data integrity issues. This issue affects Drupal Core: from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9, from 11.0.0 before 11.0.8.
