GitLab releases patches for vulnerabilities in dedicated security releases.
There are two types of security releases: a monthly, scheduled security
release, released a week after the feature release (which deploys on the 22nd
of each month), and ad-hoc security releases for critical vulnerabilities. For
more information, you can visit our security FAQ. You can see all of our
regular and security release blog posts here. In addition, the issues detailing
each vulnerability are made public on our issue tracker 30 days after the
release in which they were patched.
We are dedicated to ensuring all aspects of GitLab that are exposed to
customers or that host customer data are held to the highest security
standards. As part of maintaining good security hygiene, it is highly
recommended that all customers upgrade to the latest security release for their
supported version. You can read more best practices in securing your GitLab
instance in our blog post.

We strongly recommend that all installations running a version affected by the
