CVE-2023-46671

Credential exposure via unredacted error logging

Published Dec 13, 2023 · Updated Aug 2, 2024

Sensitive-data logging in Elastic Kibana 8.0.0 through 8.11.0 allows remote authenticated users to expose credentials in error logs. When Elasticsearch returns circuit-breaker or no-shard errors, Kibana records error messages with unredacted request headers, including authorization material. User interaction and an unhealthy cluster are required; anyone able to read the affected logs can recover Kibana system, API, or end-user credentials.
