CVE-2023-31422

Credential disclosure via error metadata logging

Published Oct 26, 2023 · Updated Sep 17, 2024

Sensitive-data logging in Kibana 8.10.0 allows attackers with log access to read credentials and request metadata after errors. When JSON layout or a pattern containing %meta is enabled, Kibana serializes the error object's request fields, including authorization headers, cookies, paths, and parameters, into logs. Exploitation requires an error plus access to affected logs; archive defaults are unaffected, while Docker and RPM/DEB defaults use the exposed layout.
