Announcing the Ember.js Security Policy

We know that building your apps on top of a framework requires trust, and that trust is never put to the test more than when security vulnerabilities are discovered.

While we're very fortunate to work on an open source project that runs in a sandboxed environment, the browser, we realize that even JavaScript applications can be vulnerable to attacks from malicious third-parties.

Ember.js is designed to mitigate common forms of attack. For example, all values rendered using Handlebars are automatically escaped to prevent XSS attacks, and developers must explicitly opt in to outputting raw HTML.

To ensure that Ember applications stay safe, today we're announcing the Ember.js Security Policy, to help security researchers and developers responsibly disclose potential vulnerabilities in Ember and Ember Data.

We have also set up the Ember.js security announcements mailing list. This is an extremely low-traffic mailing list reserved solely for announcing security releases of the framework. If you're deploying Ember to production, you or your security team may wish to subscribe.

To be clear, there are no vulnerabilities we're aware of at this time and there is not a security release forthcoming. We just take security extremely seriously and believe that having a procedure in place ahead of time will allow us to respond most effectively should the worst happen.

If you have any questions or concerns that are not addressed by the new security policy, please email us at security@emberjs.com.

I'd like to thank the Ruby on Rails security team, from whom our security policy was lifted almost wholesale, for serving as a role model for open source projects everywhere.

Lastly, my personal thanks to Aaron "tenderlove" Patterson and Tony "bascule" Arcieri for reviewing our policy and answering many of my ignorant questions.

Let's stay safe out there.
