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.
