CVE-2026-14919: Unknown Shopmonitor.io

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Unknown Shopmonitor.io: before 1.2.0 (fixed in 1.2.0)
