CVE-2024-11942: Drupal core vulnerable to improper error handling

December 5, 2024

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.
