CVE-2023-31414

Host command execution via crafted configuration payload

Published May 4, 2023 · Updated Jan 29, 2025

Code injection in Elastic Kibana 8.0.0 through 8.7.0 allows local users to execute commands through crafted configuration. Kibana's configuration-loading path interprets a specific YAML or environment payload as executable JavaScript instead of configuration data. Exploitation requires configuration write access and runs commands with Kibana process permissions; Elastic has not published the payload format or affected key.
