Summary
code16/sharp has a stored XSS via data-html-content Sanitizer Bypass
Details

Impact

The vulnerability allows an attacker to bypass the HTML sanitizer by using the data-html-content attribute in the content of a SharpEditorFormField.

Patches

The field must now explicitly configure SharpFormEditorField::RAW_HTML in the toolbar to keep this behavior. When using the RAW_HTML button, the application using code16/sharp must sanitize manually the content coming from the field. Vulnerability has been patched in version 9.22.5.

Workarounds

Sanitize every contents of editors manually (e.g. using Symfony/HtmlSanitizer)
