CVE-2026-15300 ninjew CVE debrief

Who should care

WordPress users and administrators who have installed the GEO my WP plugin, especially those using versions up to and including 4.5.4, should be aware of this vulnerability and take immediate action to update to version 4.5.5 or later.

Technical summary

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 vulnerability was caused by the plugin's use of parse_str() to read values from $_SERVER['QUERY_STRING'], which bypasses wp_magic_quotes. These values were then passed through bare esc_sql() before being interpolated into unquoted numeric positions in the proximity-search query. This allowed payloads such as `1 OR SLEEP(3)` to survive sanitization. The vulnerability was fixed in version 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.
