Note: No new Backdrop core security updates have been released since April 18, 2019. The Backdrop core security advisory emails sent from backdropcms.org on Tue Apr 23 at 10:20pm PDT refer to issues resolved on February 21, 2018 and were sent accidentally while updating security advisory content on backdropcms.org.

 

Backdrop CMS Security Team

The Backdrop CMS Security Team handles the receiving of security-related issues, fixing issues that affect Backdrop core, and coordinating with module maintainers for contributed modules.

Security Releases

Security releases will be issued for the last 2 minor releases of Backdrop, or for the last 8 months. This should give all Backdrop sites an 8-month secure window to update to the latest version.  As the community grows and as more core maintainers are added, we expect to extend security releases to the last 3 releases, or to the last 1 year.

Reporting a Security Issue

If you have found a security issue in Backdrop Core or a Contributed Project, send an email to security@backdropcms.org. Do not file an issue on GitHub if you think you have encountered a security issue. The Backdrop Security Team uses a private repository on GitHub where security issues are discussed and managed. When a security issue that affects Backdrop CMS is resolved, a release will come out on the following Wednesday.

Contributed modules, themes, & layouts

As with Backdrop CMS core issues, security-related issues for contributed projects should also be reported to security@backdropcms.org. The Backdrop Security Team will contact the module maintainers by Gitter.im, Github.com, or by email to work on resolving the security issue. The project maintainer may be temporarily invited into the private Backdrop security repository. Once a solution to the problem has been found, the security team will request the project maintainer schedule a release for the following Wednesday. The Backdrop Security Team will then create a security announcement for the security release.

The Backdrop Security Team is also watching all Drupal module security releases. When there are security releases for Drupal modules, we will work with the Backdrop maintainer to create a matching Backdrop security release within the next 24 hours. For contributed projects, our Security Team acts reactively to Drupal's security releases. This differs from Backdrop core, where the Backdrop Security Team acts proactively. 

In the event that the maintainer of a Backdrop contributed project is not available to perform a review or update of a security release, the Backdrop Security Team is authorized to make the update to the Backdrop contributed project on the maintainer's behalf.

Collaboration with the Drupal Security Team

The Backdrop community collaborates with the Drupal community on security issues. We coordinate security releases for Backdrop core and Drupal core, as well as for Drupal contributed modules that are included in Backdrop core (for example: Views). For contributed modules not in Backdrop core, we monitor recent Drupal contrib module releases and work with the Backdrop contributed module author to address the security issue as quickly as possible.

All issues that affect both Drupal and Backdrop are reported, discussed, and managed in the private Drupal Security Queue on drupal.org, where we have access to all issues that also affect Backdrop. When a security issue that affects both projects is resolved, security releases for both Backdrop and Drupal core come out on the same Wednesday.
