<br>
Project: Drupal core [1]<br>
Date: 2024-October-16<br>
Security risk: *Moderately critical* 13 ∕ 25<br>
AC:Basic/A:None/CI:None/II:All/E:Theoretical/TD:Uncommon [2]<br>
Vulnerability: Improper error handling<br>
<br>
Affected versions: >=10.0 < 10.2.10<br>
Description: <br>
Under certain uncommon site configurations, a bug in the CKEditor 5 module<br>
can cause some image uploads to move the entire webroot to a different<br>
location on the file system. This could be exploited by a malicious user to<br>
take down a site.<br>
<br>
The issue is mitigated by the fact that several non-default site<br>
configurations must exist simultaneously for this to occur.<br>
<br>
Solution: <br>
Install the latest version:<br>
<br>
* If you are using Drupal 10.2, update to Drupal 10.2.10 [3].<br>
* Drupal 10.3 and above are not affected, nor is Drupal 7.<br>
<br>
All versions of Drupal 10 prior to 10.2 are end-of-life and do not receive<br>
security coverage. (Drupal 8 [4] and Drupal 9 [5] have both reached<br>
end-of-life.)<br>
<br>
This advisory is not covered by Drupal Steward [6].<br>
