A vulnerability has been identified within Rancher where a user with the ability to create a project, on a certain cluster, can create a project with the same name as an existing project in a different cluster. This results in the user gaining access to the other project in the different cluster, resulting in a privilege escalation. This happens because the namespace used on the local cluster to store related resources (PRTBs and secrets) is the name of the project.
Advisory GHSA-8h6m-wv39-239m references a vulnerability in the following Go modules:
