Project: Drupal coreDate: 2024-November-20Security risk: Moderately critical 10 ∕ 25 AC:Basic/A:User/CI:None/II:Some/E:Theoretical/TD:DefaultVulnerability: Access bypassAffected versions: >= 8.0.0 < 10.2.11 || >= 10.3.0 < 10.3.9 || >= 11.0.0 < 11.0.8Description:
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.
Solution:Install the latest version:
- If you are using Drupal 10.2, update to Drupal 10.2.11.
- If you are using Drupal 10.3, update to Drupal 10.3.9.
- If you are using Drupal 11.0, update to Drupal 11.0.8.
- Drupal 7 is not affected.
All versions of Drupal 10 prior to 10.2 are end-of-life and do not receive security coverage. (Drupal 8 and Drupal 9 have both reached end-of-life.)
Updating Drupal will not solve potential issues with existing accounts affected by this bug. See Fixing emails that vary only by case for additional guidance.
