=== Security updates
* A field disclosure flaw was found in {es} 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. All versions of {es} before 7.9.0 and 6.8.12 are affected by this flaw.
You must upgrade to {es} version 7.9.0 or 6.8.12 to obtain the fix.
