CVE-2026-14919
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.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.
Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
