GitLab Critical Security Release: 14.0.4, 13.12.8, and 13.11.7

Learn more about GitLab Critical Security Release: 14.0.4, 13.12.8, and 13.11.7
for GitLab Community Edition (CE) and Enterprise Edition (EE).

Today we are releasing versions 14.0.4, 13.12.8, and 13.11.7 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. 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.

Arbitrary file read via design feature critical

Arbitrary file read via design feature

An issue has been discovered in GitLab CE/EE affecting all versions starting
with 13.11, 13.12 and 14.0. A specially crafted design allowed attackers to
read arbitrary files on the server. This is a critical severity issue. We will
update this blog post with the CVSS vector string once we have finished the
full assessment of the impact. We have requested a CVE ID and will update this
blog post when it is assigned.

Thanks vakzz for reporting this vulnerability through our HackerOne bug bounty
program.

Remediation

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