Security Bug Fix Policy

Atlassian makes it a priority to ensure that customers' systems cannot be compromised by exploiting vulnerabilities in Atlassian products.


The following describes how and when we resolve security bugs in our products. It does not describe the complete disclosure or advisory process that we follow.

Security bug fix Service Level Agreement (SLA)

We have defined the following timeframes for fixing security issues in our products:

  • Critical severity bugs (CVSS v2 score >= 8, CVSS v3 score >= 9) to be fixed in product within 4 weeks of being reported
  • High severity bugs (CVSS v2 score >= 6, CVSS v3 score >= 7) to be fixed in product within 6 weeks of being reported
  • Medium severity bugs (CVSS v2 score >= 3, CVSS v3 score >= 4) to be fixed in product within 8 weeks of being reported

Critical Vulnerabilities

When a Critical security vulnerability is discovered by Atlassian or reported by a third party, Atlassian will do all of the following:

  • Issue a new, fixed release for the current version of the affected product as soon as possible.
  • Issue a new maintenance release for a previous version as follows:

It is important to stay on the latest bug fix release for the version of the product you are using (this is best practice). For example if you are on Jira Software 7.5.0, you should upgrade to Jira Software 7.5.3 proactively. If a new security bug fix is released, e.g. Jira Software 7.5.4, the delta between the two versions is minimal (i.e. only the security fix), making it easier to apply. 

The critical vulnerabilities resolution process does not apply to our Atlassian Cloud products as these services are always fixed by Atlassian without any additional action from customers.


Non-critical vulnerabilities

When a security issue of a High, Medium or Low severity is discovered, Atlassian will include a fix in the next scheduled release. The fix may also be backported to Enterprise releases, if feasible. 

You should upgrade your installations when a bug fix release becomes available to ensure that the latest security fixes have been applied.


Other information

Severity level of vulnerabilities is calculated based on Severity Levels for Security Issues.

We will continuously evaluate our policies based on customer feedback and will provide any updates or changes on this page. 



What is an 'Enterprise release'?

Enterprise releases are for Server and Data Center customers who prefer to allow more time to prepare for upgrades to new feature versions, but still need to receive bug fixes. Some products will designate a particular version to be an Enterprise release, which means that security bug fixes, will be made available for the full 2 year support window.

What is a 'Feature release'?

A Feature release is a version (for example 4.3) which contains new features or major changes to existing features, that has not been designated an Enterprise release.  See the Atlassian Bug Fixing Policy for more information on our release terminology.


Why do you only cover 6 months of Feature releases for Bitbucket, Jira and Confluence?

Bitbucket Server releases very frequently, therefore 6 months covers 5-6 major versions. Since mid 2017, Jira and Confluence have moved to a similar release cadence, and are now also releasing 5-6 times per year. 

Why do other products like Bamboo, Service Desk and Fisheye/Crucible only back port to one previous major version?

Our efforts are focused on Jira, Confluence and Bitbucket Server, but we may consider extending Bamboo, Fisheye/Crucible and other products to cover additional major versions, based on the demand to do this
