Upgrade github.com/gitpod-io/gitpod/components/server/go/pkg/lib to version main-gha.27122 or higher.
Overview
Affected versions of this package are vulnerable to Cookie Tossing due to a missing __Host- prefix on the _gitpod_io_jwt2_ session cookie. This allows an adversary who controls a subdomain to set the value of the cookie on the Gitpod control plane, which can be assigned to an attacker’s own JWT so that specific actions taken by the victim (such as connecting a new Github organization) are actioned by the attackers session.
