Advisory

Source description from Wordfence Intelligence, credited to Charles Vosburgh.

The GoSMTP – SMTP for WordPress plugin for WordPress is vulnerable to Privilege Escalation in all versions up to 1.2.5. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for authenticated attackers, with custom role-level access and above, to elevate their privileges beyond those intended for their role.
