The CKEditor 4 LTS - WYSIWYG HTML editor module uses the CKEditor library for WYSIWYG editing. CKEditor has released a [security update](https://ckeditor.com/cke4/release/CKEditor-4.24.0-LTS) that on certain configurations may impact the Drupal module that bundles and integrates this code. The vulnerability is mitigated by the fact it requires: 1. [full-page editing](https://ckeditor.com/docs/ckeditor4/latest/features/fullpage.html) mode is enabled 2. or CDATA elements in Advanced Content Filtering configuration (defaults to script and style elements) are enabled. 3. An attacker must have a permission with access to the CKEditor instance. For more information, see CKEditor's security advisory: [CVE-2024-24815](https://github.com/ckeditor/ckeditor4/security/advisories/GHSA-fq6h-4g8v-qqvm): Cross-site scripting (XSS) vulnerability caused by incorrect CDATA detection
