CVE-2026-73268

Περιγραφή

A flaw was found in the cluster-curator-controller component of multicluster engine (MCE). A tenant with create or update permissions on ClusterCurator resources can inject an arbitrary Job specification. This is possible because the CreateJob() function does not validate user-controlled input when unmarshaling the spec.install.overrideJob raw extension. Successful exploitation allows the injected Job to run with the controller-s elevated privileges, leading to arbitrary code execution and privilege escalation, potentially accessing cluster-wide secrets.
