The Webform module uses the [CKEditor](https://github.com/ckeditor/ckeditor4), library for WYSIWYG editing. CKEditor has released [a security update that impacts Webform](https://ckeditor.com/blog/ckeditor-4.16.2-with-browser-improvements-and-security-fixes/).

An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit one or more Cross-Site Scripting (XSS) vulnerabilities to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.

For more information, see [CKEditor's announcement of the release](https://ckeditor.com/blog/ckeditor-4.16.2-with-browser-improvements-and-security-fixes/).
