Learn more about GitLab Release 8.13.3, 8.12.8, 8.11.10, and 8.10.13 for GitLab Community Edition (CE) and Enterprise Edition (EE)

Today we are releasing versions 8.13.3, 8.12.8, 8.11.10, and 8.10.13 for GitLab Community Edition (CE) and Enterprise Edition (EE).

These versions contain an important security fix for a critical directory traversal vulnerability, and we strongly recommend that all GitLab installations be upgraded to one of these versions immediately.

Please read on for more details.

Directory traversal via "import/export" feature: CVE-2016-9086

Jobert Abma from HackerOne disclosed a critical security flaw in the "import/export project" feature of GitLab. Added in GitLab 8.9, this feature allows a user to export and then re-import their projects as tape archive files (tar). All GitLab versions prior to 8.13.0 restricted this feature to administrators only. Starting with version 8.13.0 this feature was made available to all users.

This feature did not properly check for symbolic links in user-provided archives and therefore it was possible for an authenticated user to retrieve the contents of any file accessible to the GitLab service account. This included sensitive files such as those that contain secret tokens used by the GitLab service to authenticate users. Please see the issue for more details.

This issue has been assigned CVE-2016-9086.

Versions affected

  • 8.13.0 through 8.13.2
  • 8.12.0 through 8.12.7
  • 8.11.0 through 8.11.9
  • 8.10.0 through 8.10.12
  • 8.9.0 through 8.9.11

We strongly recommend that all installations running a version mentioned above be upgraded as soon as possible. Please note that no patch is being provided for GitLab versions 8.9.x. Those running versions 8.9.0 through 8.9.11 who cannot upgrade to a newer version should use the workaround listed below.


If you're unable to upgrade right away, you can secure your GitLab installation against this vulnerability using the workaround outlined below until you have time to upgrade.

Disable Project Import/Export via Tape Archive

Login using an administrator account to your GitLab installation and perform the following:

  1. Choose "Admin Area"
  2. Click "Settings"
  3. Under "Import Sources" disable the "GitLab export" option.
  4. Click Save

Verifying the workaround

  1. In a Browser Window, login as any user
  2. Click "Projects"
  3. Click "New Project"
  4. Enter a project name
  5. Verify that "GitLab export" does not appear as an import option

Upgrade barometer

These versions do not include any new migrations, and should not require any downtime.

Please be aware that by default the Omnibus packages will stop, run migrations, and start again, no matter how “big” or “small” the upgrade is. This behavior can be changed by adding a /etc/gitlab/skip-auto-migrations file.
