Project:
Date:
2024-October-16
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.
