Security updates

edit

  • If Elastic Endpoint (v7.9.0 - v8.10.3) is configured to use a non-default option in which the logging level is explicitly set to debug, and Elastic Agent is simultaneously configured to collect and send those logs to Elasticsearch, then Elastic Agent API keys can be viewed in Elasticsearch in plaintext.

    The issue is resolved in Elastic Stack 8.10.4.

    For more information, refer to our related security announcement.
