Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Drupal/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The Drupal project uses the third-party library [CKEditor](https://github.com/ckeditor/ckeditor4), which has released a [security improvement](https://ckeditor.com/blog/CKEditor-4.14-with-Paste-from-LibreOffice-released/#security-issues-fixed) that is needed to protect some Drupal configurations. Vulnerabilities are possible if Drupal is configured to use the WYSIWYG CKEditor for your site's users. An attacker that can create or edit content may be able to exploit this Cross Site Scripting (XSS) vulnerability to target users with access to the WYSIWYG CKEditor, and this may include site admins with privileged access. The latest versions of Drupal update CKEditor to 4.14 to mitigate the vulnerabilities.
