    Summary: Improper Control of Generation of Code in Kibana Leading to Privilege Escalation

    Details: An insufficiently validated configuration field in Kibana's Cribl integration allows an authenticated user holding Kibana Fleet management privileges to inject attacker-controlled expressions into a server-side script template, resulting in an Elasticsearch ingest pipeline being written beyond the caller's authorized Elasticsearch permissions.
