Auth bypass in Wpgmaps Wp Go Maps – Google Map, Openstreetmap, Leaflet Map
CVE-2026-12238
The WP Go Maps – Most Popular Map Plugin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 10.1.01. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to create arbitrary records in plugin database tables (maps, markers, circles, polygons, polylines, rectangles, and point labels) by supplying a WPGMZA-namespaced CRUD-backed class name via the phpClass parameter. The namespace validation check (requiring the 'WPGMZA' prefix) does not prevent exploitation because classes such as WPGMZA\Map and WPGMZA\Marker satisfy it while still triggering an INSERT into the corresponding plugin table before the route rejects the request.
