I have some concern about the latest ZK version ( that has been flagged in an cybersecurity audit.

The version of CKEditor that is actually used by ZKOSS (4.7.0) has many flaws in terms of cybersecurity: We detected ckeditor version 4.7.0, which has the following vulnerabilities: • CVE-2021-32809: XSS Clipboard plugin • CVE-2021-32808: XSS Widget plugin • CVE-2021-37695: XSS Fake Objects plugin • CVE-2021-41164, CVE-2021-41165: XSS vulnerabilities module • CVE-2022-24728: Inject malformed URL

ZKOSS PATH: /zkau/web/_zv4.7.0.0/js/ckez.wpd

Are you planning on updating that version soon, is there some alternative for me to bypass if no action are going to be taken on your side?

The latest ZK CKEditor is, which is based on CKEditor 4.18.0 and should have already fixed/patched these security issues.

If you use this add-on, update your maven pom file version string to; or download the jar file manually here: https://github.com/zkoss/zkckeditor/releases/tag/v4.18.0.0
