WP Go Maps Authorization Bypass Vulnerability

Publication date: 2026-06-19

Last updated on: 2026-06-24

Assigner: Wordfence

Description

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.

Attack-Flow Graph

Compliance Impact

The vulnerability allows unauthenticated attackers to create arbitrary records in the plugin's database tables due to an authorization bypass. This unauthorized data manipulation could potentially lead to integrity issues within the stored data.

However, there is no direct information provided about the impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.

Executive Summary

The WP Go Maps – Most Popular Map Plugin for WordPress has an authorization bypass vulnerability in all versions up to and including 10.1.01. This happens because the plugin does not properly verify if a user is authorized to perform certain actions. As a result, unauthenticated attackers can create arbitrary records in the plugin's database tables by supplying a specially crafted class name via the phpClass parameter. Although the plugin checks that the class name starts with the 'WPGMZA' prefix, this check is insufficient because some classes with this prefix still allow insertion into the database before the request is rejected.

Impact Analysis

This vulnerability allows unauthenticated attackers to insert arbitrary data into the plugin's database tables, such as maps, markers, circles, polygons, polylines, rectangles, and point labels. This could lead to data integrity issues, potential misuse of the plugin's functionality, and possibly affect the website's behavior or display by injecting unauthorized map data.
