GoSMTP < 1.2.5 - Plugin Activator+ Privilege Escalation via SMTP Settings

The GoSMTP WordPress plugin before 1.2.5 does not perform a settings-management authorization check on its SMTP configuration page, which is gated only on the GoSMTP WordPress plugin before 1.2.5-activation capability, allowing users with a delegated role below administrator to change outbound mail delivery and achieve administrator account takeover.
