Description Pedro Sampaio 2021-03-25 14:46:17 UTC

A document disclosure flaw was found in Elasticsearch when Document or Field Level Security is used. Search queries do not properly preserve security permissions when executing certain cross-cluster search queries. This could result in the search disclosing the existence of documents the attacker should not be able to view. This could result in an attacker gaining additional insight into potentially sensitive indices.

Comment 2 juneau 2021-03-31 13:21:19 UTC

Marking Hosted Services / services-assisted-installer notaffected per BU:

"assisted-test-infra is our testing infrastructure. It has nothing to do with prod code."

Comment 4 Przemyslaw Roguski 2021-04-02 12:12:47 UTC

Statement:

In Elasticsearch, Document and Field Level Security is an enterprise only feature [1]. Hence the open source version is unaffected by this vulnerability.

Cluster Logging Elasticsearch is built without X-Pack so it is not impacted by this.
