View online: https://www.drupal.org/sa-core-2024-002

Project: Drupal core [1]
Date: 2024-October-16
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:None/CI:None/II:All/E:Theoretical/TD:Uncommon [2]
Vulnerability: Improper error handling

Affected versions: >=10.0 < 10.2.10
Description: 
Under certain uncommon site configurations, a bug in the CKEditor 5 module
can cause some image uploads to move the entire webroot to a different
location on the file system. This could be exploited by a malicious user to
take down a site.

The issue is mitigated by the fact that several non-default site
configurations must exist simultaneously for this to occur.

Solution: 
Install the latest version:

  * If you are using Drupal 10.2, update to Drupal 10.2.10 [3].
  * Drupal 10.3 and above are not affected, nor is Drupal 7.

All versions of Drupal 10 prior to 10.2 are end-of-life and do not receive
security coverage. (Drupal 8 [4] and Drupal 9 [5] have both reached
end-of-life.)

This advisory is not covered by Drupal Steward [6].
