Hi,

The following vulnerabilities were published for ckeditor.

CVE-2024-24815[0]:
| CKEditor4 is an open source what-you-see-is-what-you-get HTML
| editor. A cross-site scripting vulnerability has been discovered in
| the core HTML parsing module in versions of CKEditor4 prior to
| 4.24.0-lts. It may affect all editor instances that enabled full-
| page editing mode or enabled CDATA elements in Advanced Content
| Filtering configuration (defaults to `script` and `style` elements).
| The vulnerability allows attackers to inject malformed HTML content
| bypassing Advanced Content Filtering mechanism, which could result
| in executing JavaScript code. An attacker could abuse faulty CDATA
| content detection and use it to prepare an intentional attack on the
| editor. A fix is available in version 4.24.0-lts.
