GMS-2023-140: Rancher cattle-token is predictable

January 25, 2023

An issue was discovered in Rancher versions up to and including 2.6.9 and 2.7.0, where the cattle-token secret, used by the cattle-cluster-agent, is predictable. Even after the token is regenerated, it will have the same value. This issue is not present in Rancher 2.5 releases.
