GitLab Security Release: 14.10.1, 14.9.4, and 14.8.6
Today we are releasing versions 14.10.1, 14.9.4, and 14.8.6 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.com is already running the patched version.
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.
Recommended Action
We strongly recommend that all installations running a version affected by the
issues described below are upgraded to the latest version as soon as possible.
When no specific deployment type (omnibus, source code, helm chart, etc.) of a
product is mentioned, this means all types are affected.

all versions from 1.0.2 before 14.8.6 allows a malicious actor with Developer
privileges to perform cache poisoning leading to arbitrary code execution in
protected branches. This is a high severity issue (CVSS:3.0/AV:N/AC:H/PR:L/UI:N
/S:C/C:H/I:L/A:N, 7.1). It is now mitigated in the latest release and is
