Agreed. In fact, to build on 'Erwin's example, jquery makes note of the potential for XSS when calling .html(), .append(), .after(), etc.[1] > Do not use these methods to insert strings obtained from untrusted sources such as URL query parameters, cookies, or form inputs. Doing so can introduce cross-site-scripting (XSS) vulnerabilities. Remove or escape any user input before adding content to the document. [1] http://api.jquery.com/html/ http://api.jquery.com/html/
