CVE-2026-44935 (opens in a new tab)How to fix?
Upgrade github.com/rancher/fleet/internal/cmd/controller/helmops/reconciler to version 0.12.15-rc.2, 0.13.11-rc.1, 0.14.6-rc.2, 0.15.2-rc.2 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the valuesFrom process. An attacker can gain unauthorized access to secrets and config maps across namespaces by crafting resources such as HelmOp or Bundle with references to arbitrary secrets, provided they know or can guess the name, namespace, and key. This is only exploitable if multiple tenants share the same downstream cluster in a multi-tenant environment.
Workaround
This vulnerability can be mitigated by ensuring that tenants do not have shared access to the same downstream clusters.
