CVE-2018-17244
This could allow a user to access information that they should not have access to.
Does this matter?
Lower severity and a low EPSS score (1.46%). Track it; it rarely justifies an emergency change on its own.
Description
Elasticsearch Security versions 6.4.0 to 6.4.2 contain an error in the way request headers are applied to requests when using the Active Directory, LDAP, Native, or File realms. A request may receive headers intended for another request if the same username is being authenticated concurrently; when used with run as, this can result in the request running as the incorrect user. This could allow a user to access information that they should not have access to.
