## Description

The Snapweb interface before version 0.21.2 was exposing controls to
install or remove snap packages without controlling the identity of the
user, nor the origin of the connection. An attacker could have used the
controls to remotely add a valid, but malicious, snap package, from the
Store, potentially using system resources without permission from the
legitimate administrator of the system.
