Details

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.

Is DRUPAL-CORE-2024-004 in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected drupal/core, and gives you the command that fixes it.

Scan a project free, no signup Or connect GitHub to scan every repo
