## Description

The Nexter Extension plugin for WordPress is vulnerable to unauthorized modification of user roles via the View Admin Role feature's 'reset-view' request parameter in all versions from 4.3.0 up to, and including, 4.7.6. This is due to the role_switcher_to_view_admin_as() function, which runs on the init hook, processing 'reset-view' with no login requirement, nonce verification or capability check. This makes it possible for unauthenticated attackers to remove the current roles of any account on the feature's view-as list and restore the roles stored in its saved original-role user meta, when the View Admin Role extension is enabled.
