**Elasticsearch field disclosure flaw (ESA-2020-12)**

A field disclosure flaw was found in Elasticsearch 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.

**Affected Versions**  
All versions of Elasticsearch before 7.9.0 and 6.8.12 are affected by this flaw

**Solutions and Mitigations**  
Users should upgrade to Elasticsearch version 7.9.0 or 6.8.12.

**CVSSv3: 5.3 - AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N**

**CVE ID: CVE-2020-7019**
