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.
