The remote server is hosting an outdated installation of WordPress that is vulnerable to multiple attack vectors.
Versions of WordPress prior to 220.127.116.11 are vulnerable to various flaws that may allow an attacker to perform a SQL injection attack against the remote host. Successful exploitation would allow an attacker to read/write confidential data as well as potentially execute arbitrary code on the remote database. In addition, the remote host is vulnerable to multiple cross-site scripting (XSS) flaws.
Upgrade to WordPress 18.104.22.168, or later.
