Detailsinfo

A vulnerability, which was classified as critical, was found in ninjew GEO my WP Plugin up to 4.5.5 on WordPress. Affected is an unknown code block of the component Shortcode Handler. The manipulation of the argument QUERY_STRING with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The GEO my WP plugin for WordPress is vulnerable to SQL Injection via the 'swlatlng' and 'nelatlng' parameters in all versions up to, and including, 4.5.5 The parameters are read from $_SERVER['QUERY_STRING'] via parse_str() (bypassing WordPress's wp_magic_quotes protection, which only covers $_POST/$_GET/$_COOKIE/$_REQUEST), then each is split on ',' via explode() and the resulting fragments are interpolated directly into a SQL BETWEEN clause in gmw_get_locations_within_boundaries_sql() without is_numeric() validation, (float) casting, esc_sql(), or $wpdb->prepare(). This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the site to host the Posts Locator search-results shortcode (`[gmw form="results" form_id=N]`) on a public page and to have at least one published post with an associated gmw_location row.

The weakness was presented by Naoya Takahashi. The advisory is shared for download at wordfence.com. This vulnerability is traded as CVE-2026-9757 since 05/27/2026.
