This release fixes some security issues, but not all:
https://about.gitlab.com/releases/2020/08/05/gitlab-13-2-3-released/

I opened an issue upstream for this problem:
https://gitlab.com/gitlab-org/gitlab/-/issues/233881

Maybe the vulnerability entry a003b74f-d7b3-11ea-9df1-001b217b3468
has to be updated accordingly.
