Drupal core - Moderately critical - Improper error handling - SA-CORE-2024-002

Parent Feed: 
Security advisories
Project: 
Drupal core
Date: 
2024-October-16
Security risk: 
Moderately critical 13 ∕ 25 AC:Basic/A:None/CI:None/II:All/E:Theoretical/TD:Uncommon
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.
  • 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 and Drupal 9 have both reached end-of-life.)

This advisory is not covered by Drupal Steward.
