Technical details
This is a confused deputy vulnerability (CWE-441) in Kibana's Agent Builder that allows privilege escalation through malicious agent configuration. An authenticated, non-administrative user with Agent Builder and Workflows privileges can modify shared agents to execute operations with the privileges of a higher-privileged user who subsequently interacts with the agent, potentially gaining administrative control of both Kibana and Elasticsearch. The vulnerability requires a generative AI connector to be configured and affects versions 9.4.0 through 9.4.6; it can be mitigated by disabling the Workflows feature.
Affected products
- Elastic Kibana 9.4.0 through 9.4.6
