CVE-2026-111577 Details
Description
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.
A privilege escalation vulnerability has been identified in the GoSMTP WordPress plugin, affecting versions prior to 1.2.5. The issue arises because the plugin does not implement proper authorization checks for settings management on the SMTP configuration page. This page is only protected by the plugin-activation capability, allowing users with roles below administrator to modify outbound mail delivery settings. Exploiting this vulnerability could lead to unauthorized access to administrator accounts.
Users are advised to update the GoSMTP WordPress plugin to version 1.2.5 or later.
