A vulnerability in Elastic Security's Kibana component allows authenticated users with Elastic Security feature privileges, but without read access to Elastic Defend event indices, to retrieve sensitive endpoint event data. This occurs because Kibana queries Elastic Defend event data using its internal Elasticsearch account rather than the requesting user's account, bypassing Elasticsearch index privilege checks. Sensitive information such as process command line arguments, which may include tokens, credentials, and connection strings, can be exposed. Versions 9.1.0 up to but not including 9.4.5 are affected. A patch is available to address this issue.

The Elastic Security capability that suggests existing field values while a user authors endpoint policy artifacts queries Elastic Defend event data with Kibana's internal Elasticsearch account instead of the account of the requesting user. Only Kibana feature privileges are verified, and the caller's Elasticsearch index privileges are not. An authenticated user who holds Elastic Security feature privileges but no read access to the Elastic Defend event indices can therefore retrieve field values from that data, including process command line arguments, which commonly contain tokens, credentials, connection strings, and other sensitive operational detail from protected hosts.
