What is known

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.

Business impact

Successful exploitation of CVE-2026-15300, a critical vulnerability (CVSS 9.1) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
