Name of the Vulnerable Software and Affected Versions Elasticsearch versions 7.7.0 through 7.10.1

Description The issue is an information disclosure flaw in the async search API. When an async search is executed, HTTP headers are improperly stored. An Elasticsearch user with read access to the .tasks index can obtain sensitive request headers of other users in the cluster.

Recommendations For Elasticsearch versions 7.7.0 through 7.10.1, update to version 7.10.2 to resolve the issue. As a temporary workaround, consider restricting access to the .tasks index to minimize the risk of exploitation.
