Issue
- When rendering the text fields stored for a Web Content through Web Content Templates, the resulting markup might execute undesired code if the editor has introduced executable code like:
<img src=x onerror=alert("Hello")>
Resolution
- This can easily be prevented by using the utility class
$htmlUtil.
-
$htmlUtil contains methods like $htmlUtil.escape(), which let the text saved be escaped.
