CVE-2018-18843
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Kubernetes integration in GitLab Enterprise Edition 11.x before 11.2.8, 11.3.x before 11.3.9, and 11.4.x before 11.4.4 has SSRF.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceServer-Side Request Forgery (SSRF) vulnerability in the Kubernetes integration of GitLab Enterprise Edition allows attackers to make the GitLab server perform unauthorized requests to internal resources or services.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed GitLab versionRun `sudo gitlab-rake gitlab:env:info` or access the GitLab admin dashboard and navigate to the About page (typically /admin/about) to find the exact version numberAffected if The version is 11.0.0 through 11.2.7, 11.3.0 through 11.3.8, or 11.4.0 through 11.4.3 (any version less than 11.2.8, 11.3.9, or 11.4.4 within the 11.x releases)
-
Confirm Kubernetes integration is activeCheck if any project, group, or the GitLab instance has a Kubernetes service configured. This can be done via the UI at Project Settings > Integrations > Kubernetes, or by reviewing the database table `services` for entries with `type` set to `KubernetesService`Affected if The Kubernetes integration is enabled or has been configured for any project, group, or at the instance level
You are affected only if running a vulnerable GitLab version (11.0.0-11.2.7, 11.3.0-11.3.8, or 11.4.0-11.4.3) AND the Kubernetes integration feature is currently or was previously enabled.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped11.2.811.3.911.4.4
Upgrade GitLab Enterprise Edition to version 11.2.8, 11.3.9, 11.4.4 or later to resolve the SSRF vulnerability in the Kubernetes integration.
11.4.4 (or any version >= 11.4.4)
- Back up your GitLab database and repository data before starting the upgrade
- Ensure your system meets the requirements for the target version
- For GitLab installations using Omnibus: run 'sudo gitlab-ctl stop' to stop GitLab services
- For Omnibus installations: download and install the appropriate package for your OS from GitLab's package repository
- For the specific fixed version, install either 11.2.8, 11.3.9, or 11.4.4 (11.4.4 recommended as it includes all fixes)
- Run 'sudo gitlab-ctl reconfigure' to apply the configuration
- Run 'sudo gitlab-ctl start' to start GitLab services
- Verify the upgrade was successful by checking GitLab version at /help or via 'sudo gitlab-rake gitlab:env:info'
