CVE-2024-43411

CKEditor4 is an open source what-you-see-is-what-you-get HTML editor. A theoretical vulnerability has been identified in CKEditor 4.22 (and above).

The issue impacts only editor instances with enabled version notifications. Please note that this feature is disabled by default in all CKEditor 4 LTS versions.
