CVE-2026-12238: CWE-862 Missing Authorization in wpgmaps WP Go Maps – Google Map, OpenStreetMap, Leaflet Map
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.
AI Analysis
Technical Summary
CVE-2026-12238 is an authorization bypass vulnerability (CWE-862) in the WP Go Maps WordPress plugin affecting all versions up to 10.1.01. The plugin fails to properly verify that a user is authorized to perform certain actions, allowing unauthenticated attackers to create arbitrary records in plugin database tables such as maps, markers, and polygons. The vulnerability arises because the namespace validation requiring the 'WPGMZA' prefix does not prevent exploitation; classes like WPGMZA\Map and WPGMZA\Marker pass this check but still trigger database inserts before the request is rejected. This results in unauthorized data manipulation without authentication or privileges.
Potential Impact
An unauthenticated attacker can insert arbitrary records into the plugin's database tables, potentially corrupting or polluting map-related data. There is no direct confidentiality or availability impact reported, but the integrity of the plugin's data is compromised. The CVSS score of 5.3 (medium severity) reflects the network attack vector, low complexity, no privileges required, no user interaction, and impact limited to integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch is currently documented. Until a patch is available, users should consider disabling or restricting access to the plugin to prevent exploitation. Monitor vendor channels for updates and apply any official fixes once released.
