Upgrade github.com/concourse/concourse to version 6.4.1, 6.3.1 or higher.
Overview
github.com/concourse/concourse is an automation system written in Go. It is most commonly used for CI/CD, and is built to scale to any kind of automation pipeline, from simple to complex.
Affected versions of this package are vulnerable to Authentication Bypass. Concourse, versions prior to 6.3.1 and 6.4.1, in installations which use the GitLab auth connector, is vulnerable to identity spoofing by way of configuring a GitLab account with the same full name as another user who is granted access to a Concourse team.GitLab groups do not have this vulnerability, so GitLab users may be moved into groups which are then configured in the Concourse team.
