Ember.js Security Policy

Reporting a Bug

We take security very seriously. Thank you for taking the time to responsibly disclose any issues you find.

All security bugs in Ember.js or Ember Data should be reported by email to This list is delivered to a subset of the core team who handle security issues. Your email will be acknowledged within 24 hours, and you'll receive a more detailed response to your email within 48 hours indicating the next steps in handling your report. If you would like, you can encrypt your report using our public key.

This email address receives a large amount of spam, so be sure to use a descriptive subject line to avoid having your report be missed. After the initial reply to your report, the security team will endeavor to keep you informed of the progress being made towards a fix and full announcement. As recommended by RFPolicy, these updates will be sent at least every five days. In reality, this is more likely to be every 24-48 hours.

If you have not received a reply to your email within 48 hours, or have not heard from the security team for the past five days, there are a few steps you can take:

  1. Contact the current security coordinator (Robert Jackson) directly.
  2. Contact the back-up contact (Tom Dale) directly.
  3. Post on the Ember.js discussion forums or ask in #emberjs.

Please note that the discussion forums and emberjs discord server are public areas. When escalating in these venues, please do not discuss your issue. Simply say that you’re trying to get a hold of someone from the security team.

Disclosure Policy

Ember.js has a 5 step disclosure policy.

  1. The security report is received and is assigned a primary handler. This person will coordinate the fix and release process. The problem is confirmed and a list of all affected versions is determined. Code is audited to find any potential similar problems. Fixes are prepared for all releases which are still under maintenance (See the supported LTS releases as well as the Stable channel). These fixes are not committed to the public repository but rather held locally pending the announcement.
  2. A suggested embargo date for this vulnerability is chosen and a CVE(Common Vulnerabilities and Exposures (CVE®)) is assigned for the vulnerability.
  3. On the embargo date, the Ember.js security mailing list is sent a copy of the announcement. The changes are pushed to the public repository and new builds are deployed to Within 6 hours of the mailing list being notified, a copy of the advisory will be published on the Ember.js blog.
  4. Typically the embargo date will be set 72 hours from the time the CVE is issued. However, this may vary depending on the severity of the bug or difficulty in applying a fix.
  5. This process can take some time, especially when coordination is required with maintainers of other projects. Every effort will be made to handle the bug in as timely a manner as possible, however it’s important that we follow the release process above to ensure that the disclosure is handled in a consistent manner.

Receiving Security Updates

The best way to receive all the security announcements is to subscribe to the Ember.js security mailing list. The mailing list is very low traffic, and it receives the public notifications the moment the embargo is lifted.

No one outside the core team and the initial reporter will be notified prior to the lifting of the embargo. We regret that we cannot make exceptions to this policy for high traffic or important sites, as any disclosure beyond the minimum required to coordinate a fix could cause an early leak of the vulnerability.
