WP-GeoMeta 0.3.4 - 0.3.5 - Missing Authorization to Authenticated (Subscriber+) Privilege Escalation via wp_ajax_wpgm_start_geojson_import Function

The WP-GeoMeta plugin for WordPress is vulnerable to Privilege Escalation due to a missing capability check on the wp_ajax_wpgm_start_geojson_import() function in versions 0.3.4 to 0.3.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator.
