CVE-2026-25437Network attack vector

Unauthenticated execution of unauthorized plugin action

Published Mar 25, 2026 · Updated Mar 25, 2026

Missing authorization in GZSEO 2.0.14 and earlier allows remote attackers to perform an unauthorized action through WordPress. An undisclosed function omits a WordPress capability check before performing the action; neither the endpoint nor the affected operation is public. No account or user interaction is required, but the undisclosed action prevents a more precise statement of what data or service state attackers can change.
