· Migration Library ignored the $config['migration_path'] setting.
· Input Library allowed unconditional spoofing of HTTP clients' IP addresses through the HTTP_CLIENT_IP header.
· Input Library ignored HTTP_X_CLUSTER_CLIENT_IP and HTTP_X_CLIENT_IP headers when checking for proxies.
· csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.

· Input Library triggered csrf_verify() on CLI requests.
