Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Rancher versions >=2.5.0 before 2.5.13 and >=2.6.0 before 2.6.4 do not properly sanitize credentials in cluster template answers, storing them in plaintext. Authenticated users with Cluster Owner, Cluster Member, Project Owner or Project Member roles can view the exposed credentials, passwords and API tokens through the cluster endpoints. Upgrade to Rancher 2.5.13, 2.6.4 or later; the source lists no other workaround besides limiting access to trusted users, and recommends reviewing and rotating any exposed credentials.
