# CVE-2026-65841: Jodit has cross-site scripting (XSS) via \<script\> nested in SVG that bypasses clean-html sanitization

- Also known as: GHSA-45QG-252V-3F7P
- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 4.13.6
- Published: 2026-07-31 · Updated: 2026-07-31

## Affected

- xdan jodit: fixed in 4.13.6
- jodit (npm): fixed in 4.13.6

## Description

Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. Prior to 4.13.6, Jodit's clean-html denyTags filter does not normalize foreign SVG or MathML script node names, allowing a script element nested directly in SVG or MathML to remain in editor.value and execute when content is loaded. This issue is fixed in version 4.13.6.

## What to do

- Check your stack: if you ship or depend on xdan jodit, jodit, upgrade to a fixed version (4.13.6) per the references below.
