0 CVE-2026-104355 is a high-severity authorization vulnerability in Temporal Technologies, Inc.'s Temporal Server. In multi-cluster deployments, a connected peer cluster can modify local namespaces on another cluster without proper authorization. This occurs because the receiving cluster applies inbound namespace replication updates without verifying that the namespace is global or properly authorized. An attacker controlling a registered peer cluster can alter local namespace metadata, including critical namespaces like temporal-system, potentially disrupting workflow operations. Clusters without remote clusters registered with connection enabled are not affected. Join the discussion | CVE Database V5 | 10/12/2026, 18:43:33 UTC Added: 10/12/2026, 19:04:04 UTC |
