Summary
Unintended Proxy or Intermediary ('Confused Deputy') (CWE-441) in Kibana Agent Builder can lead to privilege escalation. A non-administrative user able to edit a shared agent could cause privileged operations to be carried out under the identity of a higher-privileged user who subsequently interacts with that agent. Where the same user can also author workflows, this can extend to full administrative control of Kibana and of the Elasticsearch cluster.
