In Filament v3, a disabled RichEditor field rendered its raw state without sanitizing HTML. Where the data stored in this field's state isn't sanitized already when the form state was filled, an attacker could plant malicious HTML or JavaScript and achieve XSS that executes for users who view the form.

Please note that Filament v4 and above does not use the same mechanism for rendering a disabled RichEditor so this advisory does not apply.
