CVE-2026-120091

A flaw was found in Temporal Server, where the Kubernetes compute provider within the Worker Service constructs its client directly from user-supplied requests rather than trusted operator configurations. An authenticated remote user with read access to a namespace can exploit this vulnerability ...
