Summary

A field disclosure flaw exists in Elasticsearch prior to version 7.9.0 and 6.8.12 that may allow an unauthorized user to access sensitive fields. When executing a scrolling search with Field Level Security, if a standard user runs the same query as a more privileged user that previously executed it, the search can inadvertently expose fields that should remain hidden. This could allow an attacker to gain unauthorized access to restricted data within an index, thereby elevating their permissions and compromising the integrity of the data.

Affected Version(s)
