XSS Vulnerability with User-Supplied JSON
By default, Ember will escape any values in Handlebars templates that use double curlies (`{{value}}`). Developers can specifically opt out of this escaping behavior by passing an instance of `SafeString` rather than a raw string, which tells Ember that it should not escape the string because the developer has taken responsibility for escapement. It is possible for an attacker to create a specially-crafted payload that causes a non-sanitized string to be treated as a `SafeString`, and thus bypass Ember's normal escaping behavior. This could allow an attacker to execute arbitrary JavaScript in the context of the current domain ("XSS").

Vulnerability With {{view "select"}} Options
In general, Ember.js escapes or strips any user-supplied content before inserting it in strings that will be sent to innerHTML. However, a change made to the implementation of the select view means that any user-supplied data bound to an option's label will not be escaped correctly. In applications that use Ember's select view and pass user-supplied content to the label, a specially-crafted payload could execute arbitrary JavaScript in the context of the current domain ("XSS").
