Package : home-assistant
Type    : information disclosure
Remote  : Yes

Summary
=======

The package home-assistant before version 2021.1.4-1 is vulnerable to
information disclosure.

Resolution
==========

Upgrade to 2021.1.4-1.

# pacman -Syu "home-assistant>=2021.1.4-1"

The problem has been fixed upstream in version 2021.1.4.

is achieved by renaming the custom_components folder inside the Home
Assistant configuration folder to something else and restarting Home
Assistant.

Description

Home Assistant before 2021.1.3 allows attackers to obtain sensitive
information because custom integrations with ../ are mishandled leading
to directory-traversal.

information.
