QID 983829: Go (go) Security Update for github.com/rancher/rancher/server (GHSA-xhg2-rvm8-w2jh)

Rancher 2 through 2.2.4 is vulnerable to a Cross-Site Websocket Hijacking attack that allows an exploiter to gain access to clusters managed by Rancher. The attack requires a victim to be logged into a Rancher server, and then to access a third-party site hosted by the exploiter. Once that is accomplished, the exploiter is able to execute commands against the cluster's Kubernetes API with the permissions and identity of the victim.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
