CVE-2023-46672

Sensitive-data exposure via JSON log serialization

Published Nov 15, 2023 · Updated Feb 13, 2025

Sensitive-data exposure in Elastic Logstash 8.10.0 through 8.11.0 allows local users to read keystore-backed secrets from JSON logs. The JSON logging path writes representations of protected SafeURI and Password objects into log records instead of preserving their redacted forms. Exposure requires the non-default JSON log format and a keystore secret referenced by configuration; leaked credentials can grant access to connected services.
