Cross-tenant BundleDeployment and Secret disclosure via spoofed cluster labels during agent-initiated registration in Fleet
A cross-tenant authorization issue was discovered in SUSE Rancher Fleet. During agent-initiated cluster registration, cluster labels supplied by the registering agent, including labels in the reserved management.cattle.io/ namespace such as the cluster display name label, were applied to the resulting upstream Cluster object. Because Fleet resolves GitRepo and Bundle targets from those cluster labels, a party able to register a cluster into a Fleet workspace namespace shared with other tenants could cause its own cluster to satisfy targeting rules that administrators intended for a different cluster. This affects SUSE Rancher Fleet 0.16 before 0.16.1, 0.15 before 0.15.6, 0.14 before 0.14.10, 0.13 before 0.13.15, 0.12 before 0.12.19 and older versions.
