ckeditor4@4.14.1 vulnerabilities

ckeditor4 is a JavaScript WYSIWYG web text editor.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) due to incorrect CDATA detection in the HTML parsing module.

An attacker could exploit this vulnerability by manipulating CDATA content detection to launch an attack on the editor.

Note:

This issue is particularly relevant for instances that have enabled full-page editing mode or have allowed CDATA elements in the Advanced Content Filtering configuration, which by default includes script and style elements.
