CVE-2023-31417

Elasticsearch generally filters out sensitive information and credentials
before logging to the audit log. It was found that this filtering was not
applied when requests to Elasticsearch use certain deprecated URIs for
APIs. The impact of this flaw is that sensitive information such as
passwords and tokens might be printed in cleartext in Elasticsearch audit
logs. Note that audit logging is disabled by default and needs to be
explicitly enabled and even when audit logging is enabled, request bodies
that could contain sensitive information are not printed to the audit log
unless explicitly configured.
