Description

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.

Affected products
