The Enhanced Image (aka [image2](https://github.com/ckeditor/ckeditor4/tree/master/plugins/image2)) plugin for CKEditor in versions 4.5.10 through 4.9.1; fixed in 4.9.2, and as used in Drupal 8 before 8.4.7 and 8.5.x before 8.5.2 and other products, is vulnerable to cross-site scripting because it allows remote attackers to inject arbitrary web script through a crafted IMG element.
