Overview

github.com/rancher/rancher/server is a project that provides a container management platform built for organizations that deploy containers in production.

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). It 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. The exploiter is then able to execute commands against the victims' cluster's Kubernetes API with the permissions and identity of the victim.
