Summary
> ### CVSS: `CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC:C` (4.4)
### Problem The [WordCount](https://ckeditor.com/cke4/addon/wordcount) plugin ([`npm:ckeditor-wordcount-plugin`](https://www.npmjs.com/package/ckeditor-wordcount-plugin)) for CKEditor4 is vulnerable to cross-site scripting when switching to the source code mode. This plugin is enabled via the `Full.yaml` configuration present, but is not active in the default configuration.
In default scenarios, exploiting this vulnerability requires a valid backend user account. However, if custom plugins are used on the website frontend, which accept and reflect rich-text content submitted by users, no authentication is required.
### Solution Update to TYPO3 versions 9.5.42 ELTS, 10.4.39 ELTS, 11.5.30 that fix the problem described above.
### Credits Thanks to Sybille Peters who reported this issue, and to TYPO3 core & security team member Oliver Hader who fixed the issue.
