 GitLab Critical Security Release: 12.8.6


Today we are releasing version 12.8.6 for GitLab Community Edition (CE)
and Enterprise Edition (EE).

This version contains an important security fix, and we strongly
recommend that all GitLab installations be upgraded to one of these
versions immediately.

The vulnerability details will be made public on our issue tracker in
approximately 30 days.

Please read on for more information regarding this release.


Email Confirmation not Required on Sign-up

With the release of 12.8.0, a soft email confirmation sign-up flow was
enabled by default. For instances with sign-up enabled, users were able
to sign up and access the instance for a 2 day grace period with an
unconfirmed email address, potentially bypassing domain restrictions.
The change was reverted and is awaiting a CVE.



Versions Affected

Affects GitLab CE/EE 12.8.0 through 12.8.5.



Remediation

We strongly recommend that all installations running an affected version
above are upgraded to the latest version as soon as possible.
