CVE-2026-55678 Arc: Unauthenticated cluster node admission when `cluster.shared_secret` is unset

Arc is an open, SQL-native time-series database for telemetry. From 26.02.1 until 26.06.2, Arc Enterprise clustering accepts cluster join requests without authentication when cluster.enabled is true but cluster.sharedsecret is not configured. The defaults in internal/config/config.go set...

CVE-2026-55678

Arc is an open, SQL-native time-series database for telemetry. In Enterprise cluster deployments from v26.02.1 to v26.06.2 , the coordinator accepts cluster join requests without authentication when cluster.enabled=true but cluster.shared_secret is empty. The HMAC validation in coordinator.go is ...
