Does this matter?
Lower severity and a low EPSS score (2.23%). Track it; it rarely justifies an emergency change on its own.
Description
Home Assistant before 2021.1.3 does not have a protection layer that can help to prevent directory-traversal attacks against custom integrations. NOTE: the vendor's perspective is that the vulnerability itself is in custom integrations written by third parties, not in Home Assistant; however, Home Assistant does have a security update that is worthwhile in addressing this situation
