Overview
Affected versions of this package are vulnerable to Authorization Bypass. The --gitlab-group flag for group-based authorization in the GitLab provider stopped working whereby, regardless of the flag settings, authorization was not restricted. Furthermore, for any authenticated users, groups that were set in --gitlab-group were added to the X-Forwarded-Groups header to the upstream application.
