Description

A vulnerability has been identified within Rancher Manager where the Fleet agent wrote resources to downstream clusters using its own cluster-admin credentials instead of the ServiceAccount pinned to the deployment. It affects multi-tenancy environments where different tenants share the same downstream clusters, for example different privileged or untrusted teams inside the same organization. This could lead to overwritten configuration files. This issue affected SUSE Rancher Fleet 0.16 before 0.16.2, 0.15 before 0.15.7, and 0.14 before 0.14.11.

Affected configurations

• suse rancher fleet (>= 0.14.0 < 0.14.11) • suse rancher fleet (>= 0.15.0 < 0.15.7) • suse rancher fleet (>= 0.16.0 < 0.16.2)
