Description

Elasticsearch versions before 6.8.13 and 7.9.2 contain a document disclosure flaw when Document or Field Level Security is used. Search queries do not properly preserve security permissions when executing certain complex 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.

brXM has been updated to more recent versions of ElasticSearch libraries that are not vulnerable.

See CVE-2020-7020.

Instructions

Customers are recommended to upgrade to the latest maintenance or minor releases as indicated above. This can be done by simply incrementing the version number of the parent POM for the implementation project.
