cneumannMultiple Roles
Description#

This makes it possible for unauthenticated attackers to add additional roles to users via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Impact#
Per CVSS v3.1: confidentiality impact none, integrity impact low, availability impact none. Attack vector: network.
