Project: 
Drupal core
Date: 
2024-November-20
Security risk: 
Moderately critical 10\u2009\u2215\u200925 AC:Basic/A:User/CI:None/II:Some/E:Theoretical/TD:Default
Vulnerability: 
Access bypass
Affected versions: 
>= 8.0.0 < 10.2.11 || >= 10.3.0 < 10.3.9 || >= 11.0.0 < 11.0.8
CVE IDs: 
CVE-2024-55634
Description: 

Drupal's uniqueness checking for certain user fields is inconsistent depending on the database engine and its collation.

\n

As a result, a user may be able to register with the same email address as another user.

\n

This may lead to data integrity issues.

Solution: 

Install the latest version:

\n\n

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.)

\n

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.
