CVE-2026-14919

ShopMonitor.io

The ShopMonitor.io WordPress plugin before 1.2.0 does not properly restrict its email-rerouting test mode, gating it behind a trusted-source check that is satisfiable with client-supplied request headers, allowing unauthenticated attackers to redirect outgoing emails, including the WordPress administrator password-reset email, to an address they control and take over the administrator account.
