multiple xss

[sam2x]

Your wysiwyg editor is prone to multiple xss security vulnerabilities via 'on' events (onclick, onerror, etc.), and potentially others attributes that let's you inject javascript code. PoC : <img src='http://invalidimageurl.com/lakzelazkemlkazmlek' onerror='alert(document.cookie)'/>

Xss may let you steal sensitive session information, and thus, impersonate an authenticated user. I can't use this module since i need 'bullet-proof' user-input sanitization of a text-editor.
