MEDIUM 4.3EPSS 0.73%
Does this matter?
Lower severity and a low EPSS score (0.73%). Track it; it rarely justifies an emergency change on its own.
Description
Elastic X-Pack Security versions prior to 5.4.1 and 5.3.3 did not always correctly apply Document Level Security to index aliases. This bug could allow a user with restricted permissions to view data they should not have access to when performing certain operations against an index alias.
