CVE-2026-3222: WP Maps <= 4.9.1 – Unauthenticated SQL Injection via 'location_id' Parameter (wp-google-map-plugin)

CVE ID CVE-2026-3222
Plugin wp-google-map-plugin
Severity High (CVSS 7.5)
CWE 89
Vulnerable Version 4.9.1
Patched Version 4.9.2
Disclosed March 9, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-3222:
The vulnerability stems from two interconnected flaws in the WP Maps plugin. The root cause is the `FlipperCode_Model_Base::is_column()` method’s flawed logic for identifying column names. This method checks if a string is wrapped in backticks (`). If true, it treats the string as a column name and bypasses the `esc_sql()` escaping function. This allows attackers to inject arbitrary SQL by providing user input wrapped in backticks.

The exploitation vector is the unauthenticated AJAX handler `wpgmp_ajax_call`, registered via `wp_ajax_nopriv_wpgmp_ajax_call`. This handler allows calling arbitrary class methods, including `wpgmp_return_final_capability`. The `wpgmp_return_final_capability` function in `wp-google-map-plugin.php` (lines 232-258) receives the unsanitized `location_id` GET parameter. This parameter is passed to a database query constructed via the plugin’s model layer, which uses the vulnerable `is_column()` method. An attacker can send a request to `/wp-admin/admin-ajax.php` with `action=wpgmp_ajax_call`, `doaction=wpgmp_return_final_capability`, and a malicious `location_id` parameter wrapped in backticks containing a time-based SQL injection payload.

The patch addresses the issue in multiple locations. In `core/class.model.php`, the `is_column()` method is completely rewritten (lines 357-372). The new version no longer relies on backtick detection. Instead, it validates the input against a whitelist of actual database column names stored in `$this->allowed_columns`. This array is populated by a new `load_columns()` method that queries the database schema. The patch also adds `$this->load_columns()` calls to various model constructors (`model.location.php`, `model.map.php`, etc.) to initialize the whitelist. Additionally, the patch removes the `wp_ajax_nopriv_wpgmp_ajax_call` hook (line 74), restricting AJAX calls to authenticated users only. The `wpgmp_return_final_capability` function is also hardened with a direct database query using `$wpdb->prepare` and explicit integer casting for `location_id`.

If exploited, this vulnerability allows unauthenticated attackers to perform time-based blind SQL injection. Attackers can extract sensitive information from the WordPress database, including user credentials, plugin data, and other stored content. The CVSS score of 7.5 reflects the high impact on confidentiality and integrity with no authentication required.
