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.

The change was reverted and is assigned CVE-2020-10535.
