CKEditor5 cross-site scripting vulnerability caused by the editor instance destroying process ### Affected packages @ckeditor/ckeditor5-markdown-gfm @ckeditor/ckeditor5-html-support @ckeditor/ckeditor5-html-embed ### Impact A cross-site scripting vulnerability has been discovered affecting three optional CKEditor 5's packages. The vulnerability allowed to trigger a JavaScript code after fulfilling special conditions: a) Using one of the affected packages. In case of `ckeditor5-html-support` and `ckeditor5-html-embed`, additionally, it was required to use a configuration that allows unsafe markup inside the editor, b) Initializing the editor on an element and using an element other than `<textarea>` as a base, c) Destroying the editor instance. The root cause of the issue was a mechanism responsible for updating the source element with the markup coming from the CKEditor 5 data pipeline after destroying the editor. This vulnerability might affect a small percent of integrators that depend on dynamic editor initialization/destroy and use [Markdown](https://ckeditor.com/docs/ckeditor5/latest/features/markdown.html), [General HTML Support](https://ckeditor.com/docs/ckeditor5/latest/features/general-html-support.html) or [HTML embed](https://ckeditor.com/docs/ckeditor5/latest/features/html-embed.html) features. ### Patches The problem has been recognized and patched. The fix will be available in version 35.0.1. ### For more information Email us at [security@cksource.com](mailto:security@cksource.com) if you have any questions or comments about this advisory. |
