CVE-2020-7019

In Elasticsearch before 7.9.0 and 6.8.12 a field disclosure flaw was found when
running a scrolling search with Field Level Security. If a user runs the same
query another more privileged user recently ran, the scrolling search can leak
fields that should be hidden. This could result in an attacker gaining
additional permissions against a restricted index.
