9.0.1, and 9.0.2 are affected.

 On May 30, 2025, it was discovered that the entity risk score feature may stop persisting risk score documents if risk scoring was turned on before you upgraded to {{stack}} 8.18.0+ or 9.0.0+. This is due to a bug that prevents the `entity_analytics_create_eventIngest_from_timestamp-pipeline-<space_name>` ingest pipeline (which is set as a default pipeline for the risk scoring index in {{stack}} 8.18.0) from being created when {{kib}} starts up.
