GitLab Security Release: 16.10.1, 16.9.3, 16.8.5

GitLab Security Advisory

Today we are releasing versions 16.10.1, 16.9.3, 16.8.5 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 3rd Thursday 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 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.
