CVE-2026-58263 · Jodit Editor: Mutation XSS in jodit clean-html via a MathML/style rawtext carrier
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
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.
