CVE-2023-49923

Document disclosure via INFO-level raw-content logging

Published Dec 12, 2023 · Updated May 24, 2025

Sensitive-data logging in Elastic Enterprise Search before 7.17.16 and 8.11.2 allows remote authenticated users to expose indexed document contents. The App Search Documents API writes each indexed document's raw contents to App Search logs at the default INFO level instead of limiting them to DEBUG. Exposure requires direct Documents API use with sensitive content, and log readers can recover that content without altering documents or service availability.
