CVE-2023-31413

Credential disclosure via unredacted debug headers

Published May 4, 2023 · Updated Jan 29, 2025

Information exposure in Elastic Filebeat 7.17.9 and earlier and 8.6.2 allows local users to read HTTP authentication headers from debug logs. The httpjson input's debug logging writes Authorization and Proxy-Authorization request-header contents without redaction. Debug logging must be enabled, and the attacker must have local log access; exposure is limited to credentials carried in those headers.
