AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions Jodit Editor versions prior to 4.12.28

Description The built-in clean-html sanitizer can be bypassed using a MathML/ carrier. This technique hides dangerous elements from the sanitizer's element walk, allowing no-interaction event handlers to persist in the editor value. This can lead to Mutation XSS (Cross-Site Scripting), where an attacker-influenced HTML input results in the execution of malicious handlers, such as onload or onfocus within an <img> tag, when the output is rendered via element.innerHTML = editor.value without requiring user interaction.

Recommendations Update to version 4.12.28.
