GitLab Critical Security Release: 13.0.6, 12.10.11, 12.9.10

Today we are releasing versions 13.0.6, 12.10.11, 12.9.10 for GitLab Community
Edition (CE) and Enterprise Edition (EE).

These versions contain important security fixes, and we strongly recommend that
all GitLab installations be upgraded to one of these versions immediately.

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. 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.

CI Token Access Control

An authorization issue discovered in the mirroring logic allowed read access to
private repositories. This issue is now mitigated in the latest release and is
waiting for a CVE ID to be assigned.

Thanks to @u3mur4 for responsibly reporting this vulnerability to us.

Versions Affected

Affects GitLab EE 10.6 and later.


We strongly recommend that all installations running an affected version above
are upgraded to the latest version as soon as possible.


To update GitLab, see the Update page.
