16 New Vulnerabilities in GitLab – Update GitLab to 15.2.1, 15.1.4, and 15.0.5

On July 28, GitLab announced a security advisory in that it detailed a list of 16 new vulnerabilities in GitLab. Out of the 16 vulnerabilities, 12 are identified as medium severity vulnerabilities, and the remaining 4 are low in severity. GitLab releases patches for all the 16 vulnerabilities in 15.2.1, 15.1.4, and 15.0.5 releases. The vendor writes as a recommended action to all the GitLab users, “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.” Following this, since GitLab didn’t point out any specific deployment type as affected: omnibus, source code, helm chart, etc., the flaws affect all types of deployments. If you want to fix all 16 vulnerabilities in GitLab, you should update GitLab to 15.2.1, 15.1.4, and 15.0.5 versions.

According to GitLab, these vulnerabilities could allow the attackers to perform trigger new pipelines with the wrong author, gain unauthorized access to a private project, bypass checks on a repository, leakage of Packagist and other integration access tokens, and other attacks on the vulnerable version of GitLab. This makes it important for GitLab administrators and responds to the vulnerabilities by upgrading GitLab to 15.2.1, 15.1.4, and 15.0.5 versions as soon as possible.

What Is GitLab?

GitLab is a web-based Git repository manager with a wiki and issue tracking features, using an open-source license, developed by GitLab Inc. GitLab offers git repository management, code reviews, issue tracking, activity feeds, and wikis. GitLab provides fine-grained access control, user management, five permission levels, and branch protection. With GitLab, you can have unlimited public and private repositories with community or developer editions. You can also do continuous integration and deployment with GitLab.

GitLab Community Edition (CE) is an open-source project under the MIT License. CE is for individual developers and small teams who want to self-host their own Git repositories. A notable instance of this is the Gitlab company, which offers a hosted version of GitLab CE as well as a commercial Enterprise Edition (EE). GitLab EE adds additional features on top of CE for larger deployments. Both editions are available under either a subscription or an annual contract.

Step 1. Create backup before the upgrade

It is highly recommended to have a full up-to-date backup before you begin.

Step 2. Add GitLab official repositories

1. gitlab/gitlab-ee: The full GitLab package contains all the Community Edition features plus the Enterprise Edition ones.2. gitlab/gitlab-ce: A stripped-down package that contains only the Community Edition features.3. gitlab/unstable: Release candidates and other unstable versions.4. gitlab/nightly-builds: Nightly builds.5. gitlab/raspberry-pi2: Official Community Edition releases built for Raspberry Pi packages.
You can run this command to update the latest repositories if you have GitLab installed on your server.

$ sudo apt update

# SUSE
$ sudo zypper upgrade gitlab-ee

Note: For the GitLab Community Edition, replace gitlab-ee with gitlab-ce.
