AI-suggested

This vulnerability is fixed in Jodit Editor version 4.12.28. Users should upgrade to version 4.12.28 or later to remediate this issue. No cloud service is involved, so remediation is the responsibility of the application using the affected versions.

Description

Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. In versions prior to 4.12.28, the built-in clean-html sanitizer can be bypassed by a MathML/<style> carrier that hides a dangerous element from the sanitizer's element walk, so a no-interaction event handler survives into the editor value, potentially causing Mutation XSS. When an application supplies attacker-influenced HTML to the editor's value-set or insertion paths, the sanitized output still contains a live <img ... onload=...> (or another non-onerror handler such as onfocus). A consumer that renders that output (element.innerHTML = editor.value) executes the handler with no user interaction. This issue has been fixed in version 4.12.28.
