Detail
It must be updated to at least version 4.18.0 due to a vulnerability in the previous version:
cvssV3: MEDIUM, score: 5.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N)
CKEditor4 is an open source what-you-see-is-what-you-get HTML editor. A vulnerability has been discovered in the core HTML processing module and may affect all plugins used by CKEditor 4 prior to version 4.18.0. The vulnerability allows someone to inject malformed HTML bypassing content sanitization, which could result in executing JavaScript code. This problem has been patched in version 4.18.0. There are currently no known workarounds.
Improvement
Deployed the latest version (currently 4.19.1) from the https://ckeditor.com/ckeditor-4/download/ website using the existing build-config.js to also have all corresponding plugins back.
Test
- Check if the HTML editor still works in the application.
