CVE-2026-15300: SQL Injection (CVSS 9.1)

Description

The GEO my WP plugin for WordPress was vulnerable to SQL Injection via the 'distance', 'lat', and 'lng' parameters in versions up to, and including, 4.5.4. The values were read from $_SERVER['QUERY_STRING'] via parse_str() (bypassing wp_magic_quotes, which does not cover $_SERVER), then passed through bare esc_sql() before being interpolated into unquoted numeric positions in the proximity-search query (HAVING/SELECT clause distance math, BETWEEN bounding-box pre-filter) built by gmw_locations_query() in plugins/posts-locator/includes/class-gmw-wp-query.php. Because esc_sql() only escapes string delimiters and these positions are numeric, payloads such as `1 OR SLEEP(3)` survived sanitization. Fixed in 4.5.5 by adding an upstream is_numeric() guard that short-circuits the WHERE clause to `AND 1 = 0` when either coordinate is non-numeric, and by replacing the three esc_sql() calls with (float) casts.
