CKEditor4 low-risk cross-site scripting (XSS) vulnerability linked to potential domain takeover

Affected Packages

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. Therefore, if you use CKEditor 4 LTS, it is highly unlikely that you are affected by this vulnerability. If you are unsure, please contact us.

Impact

A theoretical vulnerability has been identified in CKEditor 4.22 (and above). In a highly unlikely scenario where an attacker gains control over the https://cke4.ckeditor.com domain, they could potentially execute an attack on CKEditor 4 instances. Although the vulnerability is purely hypothetical, we have addressed it in CKEditor 4.25.0-lts to ensure compliance with security best practices.

Patches

The issue has been recognized and patched. The fix is available in version 4.25.0-lts.
